Question

9. In humans, polydactyly (extra fingers and toes) is an autosomal dominant trait, while albinism is an autosomal recessive trait. Jason has polydactyly and albinism. His father has normal fingers and toes, but his mother has polydactyly. Christie has normal fingers and toes. She does not have albinism, but her mother did. a. What are Jason and Christie's genotypes? b. What is the probability that they have a child with both albinism and polydactyly? Show your work.

Step 1

Let P be the allele for polydactyly (dominant) and p be the allele for normal fingers and toes (recessive). Let A be the allele for normal pigmentation (dominant) and a be the allele for albinism (recessive). Show more…
