Question

A man with normal vision and a colorblind woman have children together. We can expect that _________ of their sons and _________ of their daughters will be colorblind.
A. half none
B. none half
C. all half
D. half all
E. all none

Answer 1

The answer would be E because boys inherit the Y chromosome from the dad which in this case would have the color blind trait. Girls don’t get the y from the father to get the color blind trait not be color blind because girls have 2 (X) chromosomes. Hope this helps
