Females heterozygous for the recessive second chromosome mutations pn,px,and sp are mated to a male homozygous for all three mutations.The offspring are as follows:$$\begin{array} { | l | r | }
\hline p x s p c n & 1,461 \
\hline p x s p + & 3,497 \
\hline p x + c n & 1 \
\hline p x + + & 11 \
\hline + s p c n & 9 \
\hline + s p + & 0 \
\hline + + c n & 3,482 \
\hline + + + & \underline { 1,539 } \
\hline & 10,000 \
\hline
\end{array}$$
What is the genotype of the females that gave rise to these progeny?
