In cats produce many different coat colors. Tabby fur color can be produced by AA or Aa, black is aa. Another gene pair is epistatic to the gene for fur color. When present in its dominant form (WW or Ww), this gene blocks the formation of fur color resulting in offspring with white fur (ww offspring have normal fur). Determine the proportions of offspring from the following cross:. AaWw x AaWw.
(Assume no gene linkage).
