1 Welcome to Jeopardy! Genetics Please get your blood typing lab out for me to check. Come up to my desk with your partner

2 If a boy is colorblind, he inherited it from A) His mother B) His father C) Both his mother and father D) Unable to determine

3 The ratio that Mendel found in the F2 generation was? A) 4:0 (yellow, green) B) 3:1 (green, yellow) C) 3:1 (yellow green) D) 1:2:1 (yellow, lime, green)

4 Ms. Schuckers has blonde hair and green eyes. She is describing her... A) DNA B) Genotype C) Phenotype D) Good looks

5 The pedigree below is showing a recessive autosomal trait (blue eyes). What would be the genotype of III-3?

6 What is the probability that a new baby born from I-1 and I-2 will be blue eyed?

7 If you crossed two heterozygous individuals, their offspring would have A) 0% Homozygous recessive B) 25% Heterozygous C) 75% Dominant Phenotype D) 50% Recessive Phenotype

8 A) Law of Dominance B) Law of Independent Assortment C) Law of Segregation D) None of the above

9 A) Simple Dominance B) Polygenic Traits C) CoDominance D) Incomplete Dominance

10 A Red flower is crossed with a white flower, the offspring are pink, this is an example of what kind of dominance?

11 The alternative form of a gene is called an:

12 Blood types are an example of these two types of inheritance...

13 Two plants are crossed, resulting in offspring with a 3:1 ratio for a trait. What does this suggest? A) That both parents were heterozygous B) That each offspring has the same alleles C) That the parents were pure breeds D) That blending of traits occurred.

14 Using this pedigree, individuals with the arrows are A) Heterozygous B) Homozygous Dominant C) Homozygous Recessive D) Genotype unknown

15 For a female to have hemophilia, she must have A) a Y chromosome B) an inactivated allele C) two recessive alleles D) two dominant alleles

16 Name that blood type.. A Rh B

17 II4 is what relation to III3? A) Aunt B) Father C) Uncle D) Nephew

18 If a mother has blood type A and a father has blood type B, their children s blood types could be. A) A, B, or O only B) A, B, O, or AB only C) A or B only D) O only

19 Roan cows are an example of what type of dominance?

20 Number 2 is A) Homozygous dominant B) Heterozygous C) Sex-linked D) Homozygous Recessive e E E 1 2 E 3 4

21 A women that is heterozygous for hemophilia marries a man who blood clots normally. A) What is the chance they will have a child that has hemophilia? B) What is the chance that they have a daughter with hemophilia? C) What about a son?

22 Two parents have the genotype Gg for a dominant genetic disorder. What are the chances their offspring will have the disorder?

23 Which of the following is NOT true about carriers? A) They only can be females B) They express the disorder C) They can pass on the recessive allele D) Males cannot be carriers

24 The alleles from your mother and father separating into different gametes is described in what law?

25 Name that blood type.. A Rh B

26 The ability to roll your tongue is dominant to not being able to roll your tongue. Draw a pedigree to show the inheritance of this trait, given the following family history: Grandpa Snow is a tongue roller but Grandma Snow is not. They have four children (2 sons and 2 daughters) who are all rollers. Their last daughter, Judy, married John Flake. John s parents are both rollers, but John s two sisters are non-rollers. John is a roller. John and Judy Snow-Flake have three children named Crystal Snow-Flake (a non-roller), Pretty Snow-Flake (a roller) and Jake Snow-Flake (a roller).

27 For two heterozygous individuals, their offspring would yield the phenotype ratio of and the genotype ratio of.

28 If a family has 4 girls, what are the chances of their next child being a boy?

29 The arctic fox changing fur color between seasons is caused by A) B) C) D)

30 Color blindness is recessive and sex linked. On average there are more color blind males because A) Women need two alleles to be colorblind B) Men require two alleles to be colorblind C) Women have two X chromosomes and it is inherited on the Y chromosome D) Men are more likely due to chance

31 Name that blood type.. A Rh B

32 Two roan cows are crossed. What are the phenotypic ratio of the offspring?

33 BbRr x BbRr are crossed. What are the phenotypic ratio of the offspring? A) 3:1 B) 1:2:1 C) 1:1:1:1 D) 9:3:3:1

34 Parents, one heterozygous for two traits and the other homozygous recessive for two traits, produce offspring that are homozygous dominant for both traits A) 100% B) 75% C) 25% D) 0%

35 Straight hair is recessive and curly hair is dominant. In co-dominance, the heterozygous condition would be A) Curly B) Straight C) Wavy D) Some straight hairs, some wavy hairs

36 When an organism has a heterozygous genotype, the dominant trait is seen. This can be explained by which law?

37 Draw a pedigree using the information below. Be sure to include EVERYTHING that should be in a pedigree. Then answer the question A man and woman marry. They have five children, 2 girls and 3 boys. The mother is a carrier of hemophilia, an X-linked disorder. She passes the gene on to two of the boys who died in childhood and one of the daughters is also a carrier. Both daughters marry men without hemophilia and have 3 children (2 boys and a girl). The carrier daughter has one son with hemophilia. One of the non-carrier daughter's sons marries a woman who is a carrier and they have twin daughters. What is the percent chance that either of the twins will also be a carrier? Give me the genotypes of everyone in the pedigree! (Its sex-linked don t forget!)
