The bicoid mutation (bcd^-)in fruit flies is inherited as a maternal effect recessive allele.What is the expected ratio of phenotypes in the offspring of a cross between a bcd⁺/bcd^- female and a bcd⁺/bcd^- male?

Question

Quizplus · Accepted Answer

The bicoid mutation is a maternal effect gene, meaning the phenotype of the offspring is determined by the genotype of the mother. Since the mother is bcd⁺/bcd^-, she has at least one normal allele, so all offspring will be normal regardless of their own genotype.
