One parent carries a dominant allele (A^L)that is lethal in early life in homozygotes.The other parent is homozygous for the wild type allele (A⁺)of the same gene.What is the expected dominant:wild type phenotype ratio for their offspring?

Question

Quizplus · Accepted Answer

Since one parent is heterozygous for the dominant lethal allele (A^L) and the other parent is homozygous for the wild type allele (A⁺), their offspring have a 50% chance of inheriting the lethal allele in a heterozygous state (resulting in the dominant phenotype) and a 50% chance of inheriting two wild type alleles (resulting in the wild type phenotype). Homozygous offspring for the lethal allele are not viable, so they do not contribute to the phenotype ratio.
