Bar eye (B) is a dominant and sex-linked trait of Drosophila.Curved wings (cu) and black body (bl) are recessive traits, bothfound on chromosome 2, separated by 24 map units. A homozygousBar-eyed, black-bodied female is crossed to a true-breeding maleexpressing curved wings. The heterozygous F1 female is then crossedto a male expressing all three traits. At what frequency among theF2 would you expect to find a completely wild type male?
How often would you find a Bar eyed, curved wing female?
