Figure 13.1
-In a Drosophila experiment,a cross was made between homozygous wild-type females and yellow-bodied males.All of the resulting F₁s were phenotypically wild type.However,adult flies of the F₂ generation (resulting from matings of the F₁s)had the characteristics shown in the figure above: (a)Is the mutant allele for yellow body recessive or dominant?
(b)Is the yellow locus autosomal (not X-linked)or X-linked?
