Redgreen colorblindness is caused by a mutation in a gene on

Red-green colorblindness is caused by a mutation in a gene on the X-chromosome. Colorblindness is inherited in an X-linked recessive manner. Bob (dad) is colorblind. Karen (mom) can see color.

Bob and Karen have a child named Taylor, who can see color.

Taylor has children with someone who is colorblind. They have 12 children. All the female children can see color and all the male children cannot

Taylor is most likely:

A.Male

B.Female

C.Taylor is equally likely to be male or female

Solution

Answer: female

Colorblindness is inherited in an X-linked recessive manner.

possible genotypes of color blindness

X^cX^c= heterozygous female (effected, cannot see colors)

XX^c = Homozygous femal (carrier, can see colors)

X^cY= male (effected, cannot see colors)

Bob and Karen have a child named Taylor (can see color),Bob (dad) is colorblind. Karen (mom) can see color.

so tylor should be a female, as female is carrier and she is carring the trait to next generation and her chldren are color blind
