Answer:
ppss and PPSS
Explanation:
Just as indicated in the question above, Flies homozygous for singed and purple were crossed with flies that were homozygous for normal bristles and red eyes.
And a Drosophila mutation called singed (s) causes the bristles to be bent and misshapen.
A mutation called purple (p) causes the fly’s eyes to be purple in color instead of the normal red.
Thus, the genotypes of the parental flies in Cross 1 are
PPSS and ppss
