Q1-In a cross between a white-eyed female fruit fly and red-eyed male, what percent of the female offspring will have white eyes? (White eyes are X-linked, recessive)

Muscular dystrophy (MD) is a genetic disorderthat gradually weakens the body's muscles.
Additionally, numerous genes whose expression yields enzymes are sex-linked. Glucose-6-phosphate dehydrogenase and hypoxanthine-guanine-phosphoribosyltransferase are two examples.
In the latter case, the Lesch-Nyhan syndrome results from the mutant form of the X-linked gene product.
