Answer:
so chance that their daughter is colorblind= 0%
Step-by-step explanation:
colorblindness is a sex-linked recessive trait,
let the alleles be XC- normal, Xc- colour-blind
the woman is heterozygous for this gene, so her genotype is XCXc
man is normal so his genotype is XCY
( man is XY and woman is XX)
XCY * XCXc
see table at the attachment corner below
probability of getting a colorblind progeny given that progeny is a girl= number of colorblind girl/total number of girls=0/2=0
so chance that their daughter is colorblind= 0%
