Eye pigment in a particular strain of fly is determined by two genes. An autosomal gene that controls the color of the pigments
Semenov [28]

RrXtXt×RrXTY is representing the cross between the white eyed female and red eyed male.

Option D

<h3><u>Explanation:</u></h3>

The genes that are discussed here both are completely dominant over their recessive alleles. In the autosome, the dominant R gene is responsible for red eye and recessive r gene is responsible for sepia eye. But in allosome, the dominant T gene allows the eye colour to be expressed and the recessive t gene doesn't allow eye colour to be expressed and makes it white.

As the female do have 2 X chromosomes and the female is white eyed, then both the chromosomes of female have t gene.

As the male is red eyed and have one X chromosome, so the male must have atleast one R gene in autosome to make the eye colour red and must have T gene in his X chromosome to make it appear in phenotype.

So the most possible cross that is given here is RrXtXt×RrXTY.
