A woman who is heterozygous for the gene

Fernanda Morse · Answer 2

A women who is heterozygous for the gene

Explanation:

A recessive gene is expressed only in homozygous genotype. Since the women should not express the disease, they cannot have homozygous recessive genotype. Women with heterozygous genotype will not be affected with the disease but will deliver one copy of their recessive allele to the offspring. So, a woman who is heterozygous for the gene could have passed the recessive lethal allele to offspring but not have the disease herself.
