Write a paragraph explaining why a color-blind man who has three daughters and one son with normal color vision might have two grandsons who are color-blind. Use the terms in the vocabulary box in your answer. Underline each term.
PLEASE HELP!!!!! last question I need
Mother must be homozygous for normal vision, which means the daughters would have been carriers (heterozygous), allowing them to pass the recessive colorblind genes to their sons. (Remember that colorblindness is X-linked.)
I'll let you rephrase the information to include the above terms.
