1 Station 1 Using the cards, match the vocabulary word with its definition. If there are any words you do not know, write them down if you have time!
2 Station 2 Answer the following questions on a separate sheet of paper. Your answers should be detailed and thoughtful. 1) Can a mother and father with brown eyes have a child with blue eyes? Create a Punnett Square as proof that this is possible and explain your answer. 2) Explain the difference between homozygous dominant, homozygous recessive and heterozygous. Give an example of each. 3) Explain the difference between chromosome and gene mutations. Give an example of each.
3 Station 3 4) Which of the following represent homologous chromosomes that are heterozygous for the trait?
4 Station 3 5) When snap dragons are mated, 25% of the offspring are red, 50% are pink, and 25% are white. Because the parent flowers make offspring that is a blend, the trait for flower color is an example of.
5 Station 3 6) Examine the table below and answer the questions that follow: Cross Number Offspring Genotype Offspring Phenotype Heterozygous (Ss) 527 Short Haired Homozygous Dominant (BB) 347 Heterozygous (Bb) 682 Black Heterozygous (RW) 445 Homozygous (WW) 427 Red and White 445 White Homozygous Dominant (PP) 665 Heterozygous (Pp) 315 Homozygous Recessive (pp) 325 Purple 665 Lavender 315 White
6 Station 3 6a) Based on the table, what are the genotypes of the parents for Cross 4? 6b) Based on the table, what is the inheritance pattern for Cross 3?
7 Station 4 7) Examine the table below and answer the questions that follow: P Generation F1 Generation F2 Generation Spotted Skin x Plain Skin 100 Plain Skin 140 Plain Skin 60 Spotted Skin Short Fur x Long Fur 500 Short Fur 650 Short Fur 350 Long Fur Yellow Fur x Black Fur 400 Yellow Fur 620 Yellow Fur 180 Black Fur a) Which trait is dominant for skin appearance? b) Which trait is recessive for fur color?
8 Station 4 8) The genes for hemophilia are located on the X chromosome. It is a recessive disorder in the blood in which the blood does not clot. The mother has hemophilia and the father is normal for blood clotting. What is the probability that a daughter will have hemophilia? Show your work with a Punnett Square.
9 Station 4 9) Within the skin cells of a child, a mutation occurs that causes skin cancer. Who with this mutation affect? 10) A mother is heterozygous for blood type A and the father is heterozygous for blood type B. What is the probability that their child will be blood type O? Show your work with a Punnett Square.
10 Station 5 11) When you see a range of phenotypes like skin color, it is a good indicator that the inheritance pattern being displayed is controlled by multiple alleles. What is this called? (p. 242) 12) If an organism exhibits BOTH dominant traits from the parents, the trait is controlled by. (p. 184) 13) Tallness (T) is dominant over shortness. Write the genotype of a pea plant that is heterozygous.
11 Station 5 14) In rabbits, black fur (B) is dominant over brown fur (b). Cross two heterozygous rabbits. Show your work with a Punnett Square. a) What color fur would the parents have? b) What color fur would 3 of the offspring have?
12 Station 6 15) Cross a heterozygous individual with a homozygous recessive individual. How many different phenotypes would the offspring have?
13 Station 6 16) In humans, having freckles (F) is dominant over not having freckles (f). The inheritance of these traits can be studied using a Punnett Square similar to the one shown below. a) What would the genotype of the offspring be in box 3? b) What would the genotype and phenotype of the offspring in box 1 be? c) What is the probability of the couple having children with freckles? Without freckles?
