Show transcribed image text Bicoid is a strict maternal-effect gene in Drosophila; that is, it is not expressed in the zygote. Recessive mutations inbicoid (bcd) cause embryonic death by preventing the formation by anterior structures, such as the brain. Unlike bicoid, the fruitless (fru) gene is a sex-influenced gene that encodes a zine-finger transcription factor that regulates the genes for male sexual behavior. Males homozygous for the fur mutation are sterile and court other males in contrast to females, which are unaffected. For each cross, calculate the probability of producing a female that can give rise to viable offspring that are fertile assuming that the two genes are 1) not linked 2) linked.
