1 Student ID#: Student Name: Ophelia Dominguez Team Name: WANNA BEE s Lab Assignment #: Lab #2 Lab Title: Personal Genetic Profile Date: Purpose / Objective(s): Profile common genetic traits in myself and relatives in my family tree * (Please note, some information is limited, as I am adopted, and have minimal information on my birth mother). Profile common genetic traits in Bio 105 class Determine patterns of genetic inheritance in my family tree Compare female traits of my family to female classmates Compare male traits of class with my family s males Hypotheses: The following genetic traits should demonstrate independent genetic inheritance patterns within my class and family: Females in Bio 105 should have genetically diverse traits expressed Males in Bio 105 should have genetically diverse traits expressed Females in my family will not resemble traits of class females Males in my family will not resemble traits of class males A genetic trait that exists with myself and my children, Gorlin s Sign (touching tongue to nose) will be a minority in class data, as in society, it s prevalent only in 10% of the population.. I learned about Gorlin s sign in my Rheumatology textbook, and it is also noticed up to 50% in people with hyper flexible Joints Ehler s Dalos Syndrome. As I m adopted, I m curious to see what traits I ve passed onto my children. I ve been diagnosed with Ankylosing Spondylitis, and curious to see if my children will also be susceptible to this disease. Materials / Subjects / Specimens;. A total of 39 students and one teacher in Bio 105 class were asked their common genetic traits and a few extra traits for extra credit. They were recorded and added class tables of data.(see Tables #2 and 3) I recorded my personal genetic information (see table# 1) I asked generic traits among my family and recorded in a table o Self o Birth Mom (limited data) Page 1 of 23 LAB Report 2 Genetic Profile Good Example

2 o Son o Daughter o Ex-Husband o (see tables #6 and 7 ) Methods / Tools / Instrumentation / Procedures; The standard generic traits asked were: o Bent Little finger o Hitch Hiker Thumb o Interlacing Fingers o Pigments iris o o o o Astigmatism Far-sighted Widow s peak Mid-digital Hair o o o o Free Vs Attached Ear lobe Tongue Rolling Dimpled Chin Freckles The extra credit genetic traits asked were: o Gorlin s sign (touching tongue to nose; prevalent in Ehler s Danlos Syndrome, joint hypermobility, some rheumatic diseases and disorders) o Curly or Straight Hair o Morton s Toe (where the 2 nd Phalanx is longer than the 1 st Phalanx, also known as the Hallux in Latin or Big Toe in common speech o Handedness: Right or Left-Handedness o Nose: Thin or Thick Nasal above nostril Gorlin s Sign Large Nose Morton s Toe Results Table #1 summarizes personal genetic traits of Cathy OPHDM Table #2 summarizes the total sum of Biology 105 class common and Extra Credit genetic traits Table #3 summarizes the Biology 105 class percentage in common genetic traits and Extra Credit genetic traits Table #4 summarizes common genetic female traits in my family and Extra Credit genetic traits Table #5 summarizes common genetic male traits in my family and Extra Credit genetic traits Page 2 of 23 LAB Report 2 Genetic Profile Good Example

3 Table #6 summarizes OPHDM Family females percentages of genetic traits Table #7 summarizes OPHDM Family male percentages of genetic traits Analysis: Graphs Figure 1 shows a graph of Biology Class Females vs. Class Males. An interesting observation is that of cumulative classes, more females than males have genetic traits of bent little finger, straight thumb, tongue rolling, dimples and pigmented eyes than class males. Figure 2 shows a graph of Biology Class Females vs. OPHDM Family Females. 10 of the class females had Morton s Toe, while zero of my family had this feature of the 2 nd toe or phalanx being longer. Figure 3 shows a graph of Biology Class Males vs. OPHDM Family Males. Class males were quite high for bent little finger, while my family was zero for males. Mid-digital hair was also quite high for class versus OPHDM males. Figure 4 shows a graph of OPHDM Family Females vs. Family Males. Females have thin noses. All of us have pigmented irises (blue) and the hitchhiker thumb. None have a bent little finger. Males have Widow s Peak and mid-digital hair but women do not. Figure 5 shows a graph of OPHDM Family Males and Females, and Biology Class Males and Females. Mid-digital hair is even for class females and males. Class has a much higher rate of brown or pigmented eyes than does my family Same with the Morton s Toe feature (2 nd toe or 2 nd phalanx is longer than 1 st toe or phalanx Figure 6 shows a graph of Biology Class Males vs OPHDM Family Females. Class males are much higher proportionally than family females with pigmented eyes, bent little finger, and Widow s Peak. Family females were higher proportionally with thin noses versus class males with wider noses. Figure 7 shows a graph of Biology Class Females vs OPHDM Family Males. Class females were higher proportionally than family males for Morton s Toe. Right-Handed dominant was proportional to society of 90% right-handed and 10% left-handed.

4 Analysis: Tables Table #1 shows my personal data. I do have specific recessive traits, such as being left-handed and Gorlin s Sign, which reflect a higher risk of having autoimmune diseases (I m diagnosed with Graves Disease, Sjogren s Syndrome, and Ankylosing Spondylitis),. My children have the Gorlin s Sign and Graves Disease antibodies, but are right-handed. They have not shown signs of any autoimmune diseases yet. Table #2 shows the totals of Cumulative Biology 105 students with Dominant Genetic Traits. I m surprised to see such high numbers of dominant traits such as eye pigmentation, Far-sightedness, and hair on the mid digit. Left-handedness vs. right-handedness follows statistical norms (90% right, 10%left), with 36 students being right handed and 4 being left handed. Statistically surprising was the statistics for the class on Gorlin s sign (being able to touch your tongue to your nose). Class numbers showed 13/39 with this trait, which is 33%. Humans average 8-10% for this trait. As the class total was for 39 people, it may have just been a small number total; perhaps over students would have statistics of around 10% instead. Table #3 shows same observations as above in Table #2, this table with the percentages. For hair, Widow s peak is dominant, but in class, it shows as the minority, with only 26%. Similar with dimpled chin/cheek at just 28%, where dimples are a dominant trait. Perhaps the school pool of students from specific ethnic backgrounds of Hispanic and Asian vs. European or Caucasian descent shifted the class majority. Table #4 shows the OPHDM Family Female Genetic Traits. I am the only left-handed member, my children are right handed, my birth mother was also right handed. So possibly my birth father was left handed, or grandparents on either sided had the left handed recessive trait and passed this onto me. My daughter got her dimple from her Dad (he has the chin cleft) and the freckles from us both. Table #5 shows the OPHDM Family Male Genetic Traits. The males are all right handed, have blue eyes, free earlobes, straight little fingers, hitchhiker thumbs, are farsighted, with freckles, and no Morton s Toe present. My son did get the tongue rolling trait from me and can also touch his tongue to his nose, whereas his Dad s tongue does not roll (recessive trait) and cannot touch his tongue to his nose. Table #6 shows the Percentages of OPHDM Family Females with Genetic Traits, similar to Table #4. All are blue eyed. My birth mother and I both wore glasses (near-sighted) whereas my daughter does not need glasses. No females have the dominant trait of the Widow s Peak. My daughter and I each have wavy hair. My birth mother had straight hair. So possibly my birth father had curly or wavy hair, or a grandparent on either side had this feature and passed it down to us. Table #7 shows Percentage of OPHDM Family Males with Genetic Traits, similar to Table #5. Males have straight hair. Only one has dimples and middigital hair.

23 Observations: 1. Unfortunately, there is limited information on my biological family as I am adopted. I m curious to get more information about my biological family. I did find out some information about my birth mother, but she died back in 1989 from complications due to breast cancer. Coincidentally, my adopted Mom had breast cancer in She is a survivor. 2. Cumulative Biology 105 class students provides a large pool of genetic traits for analysis. The class showed a near average of 50% for bent little finger, while my family females were zero. 82% of the class was dominant for brown eyes, while 100% of my family has the recessive genetic trait for blue eyes. I m surprised to see such high numbers of dominant traits such as eye pigmentation, Far-sightedness, and hair on the mid digit. 3. My hypothesis of the class having society s norm of 10% positive for Gorlin s sign (touching tongue to nose) was proven incorrect. Class came in much higher at 33%. This could be due to the smaller sample, or perhaps the genetic diversity of Asian and Mexican students includes the Gorlin s sign. That would be interesting to research. Many Asians will have their faces turn red after drinking alcohol, while most Caucasians do not, so there are differences racially. 4. The class statistic for right handedness was same as society with 90%. My family was close, with 80%, but with a smaller pool of candidates. I wonder if this recessive gene will possibly be inherited by my grandchildren. I wish I had genetic data available in a national data bank I could access on my birth father. As left handed people are more likely to get autoimmune diseases, I d be curious to see classmates in years to see if they have anything autoimmune-related. 5. In the future, I d also like to see about doing genetic DNA testing for myself and kids to find more out about our genetic background. I have Graves Disease, Sjogren s and Anklyosing Spondylitis. The kids have the thyroid antibodies for Graves Disease but are not active (TSI, Thyroid Stimulating Immunoglobin). My Spondylitis is HLA-B27 negative, or seronegative. It s possible that another HLA will test positive for me or them with additional testing. Another thing is to also look at monozygotic twin studies (identical twins/1 egg splitting). Rates for autoimmune diseases like MS, RA, and IBD among monozygotic twins can be 25-50%. Page 23 of 23 LAB Report 2 Genetic Profile Good Example
