A Drosophila male from a true­breeding stock with
scabrous eyes was mated with a female from a true­breeding stock
with javelin bristles. Both scabrous eyes and javelin bristles are
autosomal traits. The F1 progeny all had normal eyes and bristles.
F1females from this cross were mated with males with both scabrous
eyes and javelin bristles. Write all the possible phenotypic
classes of the progeny that could be produced from the cross of the
F1 females with the scabrous, javelin males, and indicate for each
class whether it is a recombinant or parental type. ​
