Question

a. this situation can not occur
b. the father has a dominant brown-eyed allele
c. the mother has a dominant brown-eyed allele
d. the husband is not the father of the child

Answer 1

The correct answer is B. If a blue-eyed man is married to a blue-eyed woman and the woman gives birth to a brown-eyed child, the most likely explanation for this situation is that the father has a dominant brown-eyed allele.

Step-by-step explanation:

With the color of the eyes, it is not always the dad's gene that determines whether he will have clear eyes or not, here comes the combination of both, but if Dad has certain traits, he is more likely to inherit it, like brown eyes, which are inherited more strongly than clear eyes.
