In fruit flies, the gene for eye color is sex-linked (X-chromosome)and red eye color is dominant over white. The gene for body coloris an autosomal trait with gray dominant over black. A heterozygousred-eyed, pure-bred gray female mates with a heterozygous gray malewho has red eyes. What is the probability that any of the offspringproduced have he following traits? You must show your work (i.e.Punnett squares) to get credit.

a. Red eyes
b. gray body
c. white eyed female
d. white eyes and heterozygous gray body
e. female and red eyed gray body

If you are provided with a stock of pure-breeding (i.e., homozygous) wild flies and another stock of pure-breeding Bar flies, how could you determine if the Bar allele is sex-linked or autosomal, dominant or recessive? In other words, outline the genetic crosses you would perform (which flies would you mate together), whereby the offspring of said crosses would inform you of the pattern of inheritance for the Bar allele. What results would you look for to tell you if the allele is sex-linked or autosomal, dominant or recessive? whats seen on online is not helpfull and incomplete
