The bicoid (bcd) gene in drosophila melanogaster has a role in establishing the polarity of the insect larva early in development. when homozygous in the maternal parent, a mutation in bcd has no effect on the parent but causes failure of anterior development in all of the offspring. the developing larvae have two abdomens, lack a head and fail to develop fully to adulthood. suppose a heterozygous (bcd + /bcd - ) female is testcrossed with a homozygous (bcd - /bcd - ) male.
