Question

Suppose a blue-eyed woman and a brown-eyed man had a child with blue eyes.
Answer all of the following:
A. What would the genotype of the man have to be? Why is this the case?
B. What is the probability of this couple having a second child with blue eyes?
C. What are the possible genotypes of the man's parents (show all)?
D. What are the possible genotypes of the woman's parents (show all)?

Answer 1

A: could be (BB) or (Bb) an OCA2 gene. It is a more likely chance that most children will have brown eyes over blue because brown is dominant and blue is recessive. B: that is a question that can be asked if the parents decide to have another little one. Most likely the second baby will get brown eyes. C, the possible eyes the man's parents could have is both brown eyes or one parent with brown eyes and the other with blue. And the women's parents could both possibly have blue eyes or one may have brown. I hope this helps you.
