I will mark brainliiest if it's would be appropriate answer
please don't write rubbish​

Answer 1

Answer:

Colour blindness is an X-linked recessive disorder. In the above question, Mother is a carrier . Therefore, her genotype must be X^C X. The father is normal, hence his genotype must be XY. By using punnet square, the possible genotypes and phenotypes in next generation will be:

 X Y

X^C X^C X X^C Y

X XX XY

The possible genotypes are- X^C X, X^C Y, XX and XY. The four possible phenotypes are- Carrier Daughter (X^C X), Affected son (X^C Y), Normal daughter (XX), Normal son (XY).
