A Cross Was Made Between Homozygous Wild-Type Female Drosophila and Yellow-Bodied

Short Answer

A cross was made between homozygous wild-type female Drosophila and yellow-bodied male Drosophila.All of the resulting offspring were phenotypically wild type.Offspring of the F₂ generation had the following phenotypes:
$\begin{array}{lcc} \text { Sex } & \text { Phenotype } & \text { Number } \\\hline\\\text { male } & \text { wild } & 96 \\\text { male } & \text { yellow } & 99 \\\text { female } & \text { wild } & 197\end{array}$ Based on this information:
a) Is the mutant gene for yellow body behaving as a recessive or dominant?
b) Is the yellow locus on an autosome or on the X chromosome?
