4. The two factor cross in which the two traits are on different chromosomes. Here, we will look at the inheritance of two traits in dogs, hair color and hair texture. We will assume that these traits are located on two different chromosomes. Black hair is dominant and yellow hair is recessive. Wiry hair is dominant and smooth hair is recessive: Hair color: B black, b yellow Hair texture: W wiry, w smooth a. What are the possible gametes for two parents, both of whom are heterozygous both traits (e.g. BbWw)? for BbWw b. What are the expected phenotype ratios for the kids of these two parents? B" "Wo b. What are the possible gametes for a parent who is homozygous recessive for both traits? bbww Bbww d. What are the expected phenotype ratios of the children if dad is heterozygous for both traits, and mom is homozygous recessive for both traits? baww 5. The two factor cross in which the two traits are close together on the same chromosome. Now let's pretend that hair color and texture are close together on the same chromosome. As a reminder: Black hair is dominant (B), and yellow hair is recessive (b) Wiry hair is dominant (W), and smooth hair is recessive (w) a. What are the possible gametes for two parents, both of whom are heterozygous for both traits (BbWw), with B and W on one homolog and b and w on the other homolog? Bbuw What are the expected phenotype ratios for the kids of these two parents? b. b. Compare these phenotype ratios with the children of the two double heterozygote parents in the Question 4. What do you notice?
