A normal woman marries a man whose mother is colorblind. What is the probability of their children having color blindness? What percent is phenotypically normal
Heather was surprised to discover that she suffered from red-green colorblindness. She told her biology professor, who said, “Your father is colorblind, too, right?” How did her professor know this? Why did her professor not say the same thing to the colorblind males in the class?
A young boy is color blind. His one brother and five sisters are not. The boy has three maternal uncles and four maternal aunts. None of his uncles’ children or grandchildren is colorblind. One of the maternal aunts married a colorblind man, and half of her children, both male and female, are colorblind. The other aunts married man who have normal color vision. All their daughters have normal vision, but half of their sons are color blind.
a) is either of the boy’s parents colorblind?
b) which of the boy’s four grandparents transmitted the gene for colorblindness?

- Albinism is inherited through a recessive allele (a). Juan has normal skin color. His Mom and Dad also have normal skin color. Juan marries Paige, who also has normal skin color. Surprisingly, their first child is an albino. What is everyone's genotype?arrow_forwardAlbinism is a recessive trait. Two individuals who both have normal pigmentation have one child out of three who has albinism (without melanin pigmentation). What are the genotypes of this child's parents?arrow_forwardMary and Ron don't have albinism. However, is it possible for them to have a child with albinism? Explain. Stephanie has normal color vision. Her husband Chris also has normal color vision. They have a son that is color blind and a daughter that has normal color vision. What is the genotype of the mother, father, son and the daughter? Andy and Anne do not have polydactyl. Is it possible for them to have a child with polydactyl? Explain. When examining a pedigree chart, I notice that only males are affected. What does this tell me about the inheritance pattern? A man with blood type A marries a woman with blood type B.
