Question

Quizplus · Accepted Answer

When both parents are carriers of the recessive gene for blonde hair, there is a 25% chance that their offspring will inherit the recessive gene from both parents, resulting in blonde hair. This follows Mendelian genetics principles, where the offspring's genotype possibilities are 25% homozygous dominant (brown hair), 50% heterozygous (brown hair but carries the blonde gene), and 25% homozygous recessive (blonde hair).
