Larika and James are very excited about the fact that their first child is due to be born any day.Larika talks endlessly about how much she hopes that the baby will have her green eyes,and James (who has brown eyes)shares her hope,but does not really think it will happen.Why?
A) Because James knows that green eyes are a mutation of blue-eye genes, and because neither parent has blue eyes it is not possible for the baby to have green eyes.
B) Because James knows that green eyes are the result of a heterozygous allele pair, and because he has brown eyes there is no way he can contribute to a baby having green eyes.
C) Because James knows that everyone in his family has brown eyes, and that because green eyes are recessive and brown eyes are dominant the baby has very little chance of having brown eyes.
D) Because James knows that green eyes are recessive, and thus cannot be passed from mother to baby.

Question

Quizplus · Accepted Answer

Green eyes are recessive to brown eyes, meaning both parents must carry the gene for green eyes for their child to potentially have green eyes. Since James has brown eyes and seems to imply a genetic dominance of brown eyes in his family, it's less likely their child will have green eyes if he doesn't carry the recessive green eye gene.
