You are performing a fruit fly cross similar to those that Thomas Hunt Morgan performed. Unfortunately, you forgot to write down the parents of your cross. You count the progeny, and find you have $60$ red$-$eyed males, $120$ red$-$eyed females, and $60$ white$-$eyed males. Assuming that all genotypes from this cross should have equal survival rates, what are the genotypes of the parent flies?

none is correct

$x^{w}Y$ and $x^{w+}{x}^w$

$x^{w+}Y$ and $x^w{x}^w$

$x^{w+}Y$ and $x^{w+}{x}^w$

$x^{w}Y$ and $x^{w+}{x}^{w+}$
