WebThis problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: In a cross between a white-eyed female fruit fly and red-eyed male, what percent of the female offspring will have white eyes? (White eyes are X-linked, recessive). Explain your answer to get full credit. WebThe fruit fly, Drosophila melanogaster, has been used for decades as a genetic model for unraveling mechanisms of development and behavior. In order to efficiently assign gene functions to cellular and behavioral processes, early measures were often necessarily simple. Much of what is known of developmental pathways was based on disrupting …

white, abbreviated w, was the first sex-linked mutation discovered, found in the fruit fly Drosophila melanogaster. In 1910 Thomas Hunt Morgan and Lilian Vaughan Morgan collected a single male white-eyed mutant from a population of Drosophila melanogaster fruit flies, which usually have dark brick red compound eyes. Upon crossing this male with wild-type female flies, they found that the of… WebWild-type fruit flies have dark red eyes, but there are recessive alleles of this eye color gene (called the white gene) that cause individuals to have white eyes. As a recessive trait, the white eye phenotype is masked by the presence of a wild-type (red encoding) allele. If the white gene were on an autosome, it would exhibit classical ...

Many genes can affect Drosophila eye pigments. Some of these cause the absence of the normal brown pigment and appear red, such as this fly on the left. Others lack bright red pigment and appear ruby or brown. Still others, like this one on the right, may lack both pigments and appear white.
