Question

A woman with normal color vision has a colorblind daughter. What are the genotypes & phenotypes of both parent?

Answer 1

assume C is normal and c is colorblind.
the mother-Cc
the father-Cc
they both have to have a recessive gene in order to have a colorblind daughter.

Answer 2

Color blindness is a sex linked trait-- the gene is located on the X chromosome. Mother is a carrier (has one normal X and one defective X. The father is colorblind (One defective X and a regular Y). The daughter inherited defective Xs from each parents (2 defective X)

Phenotypes: Mother-- X^C X^c Father-- X^cY Daughter X^c X^c

Answer 3

Colorblindness is by way of a recessive allele. those are no longer FLAWS. this is amazingly troublesome to envision somebody's reaction who needless to say does no longer be attentive to Genetics. Colorblindess is a intercourse-appropriate gene. it rather is located on the X chromosomes. If a baby lady is colorblind she could be XcXc (there is one c for each X chromosome cutting-edge and pretend those c's are subscripts) the mummy isn't colorblind, subsequently she is XCXc And the father, purely having one X chromsome, will bypass that X to his daughter, meaning he could be XcY.
