(a) A Drosophila male from a true-breeding stock with scabrous eyes was mated with a female from a true-breeding stock with javelin bristles. Both scabrous eyes and javelin bristles are autosomal recessive traits. The F1 progeny all had normal eyes and bristles. F1 females from this cross were mated with males with both scabrous eyes and javelin bristles.

QUESTION:Suppose you mated the F1 females from the cross in part (a) to wild-type males. Why would this cross fail to inform you whether the two genes are linked?
