Solution

F. A female child must have genotype XcXc for her to being color blind. Color blind is a X linked recessive disorder. Females carry two X chromosome. For female child to be color blind, both of her two X chromosomes must have a mutated color blind gene in order to express color blind triat in her. If only one of her X chromosome is mutated, it will not.produce color blind triat in her. However such a female will be carrier for color bkind triat.

G. For color blind male child , genotype will be XcY. As males have only one X chromosome, they are therefore hemizygous for X linked triats. If this X linked gene is mutated in males , it will produce color blind triat.
