Drosophila eye color is an X-linked trait. Red eye color is dominant, and white eye color is recessive. Which Punnett square sho

Anestetic [448]

The genotype of the mother must be heterozygous.

<h3>Punnet' square</h3>

In order to obtain a probability of 25% red-eyed males from the offspring, the mother must be heterozygous for the trait. The father can be of any genotype.

Thus, the likely genotype combination that will result in 25% red-eyed males are:

$X^RX^r$ x $X^RY$

$X^RX^r$ and $X^rY$

When you cross the first one above, the genotype of the offspring would be $X^RX^R, X^RY, X^RX^r, X^rY$ .

The second cross will give offspring with the genotypes $X^RX^r, X^RY, X^rX^r, X^rY$

Both crosses give a 25% chance of producing re-eye males.
