For cn and st alleles, when crossed to a white-eyed female, produced only wild-type and white-eyed progeny. Explain the likely chromosomal constitution of this male.

Chromosomal Constitution

Explanation:

They have a deformity in their "white" quality, which ordinarily delivers the red colors in the eye. In these flies, the white quality just works in part, delivering less red shades than it should. These flies have white eyes.  It conveys the forerunners of the red and darker eye shading colors, guanine and tryptophan, into the creating eyes during pupation. White-peered toward flies are not visually impaired rather they are effectively briefly blinded by splendid light at specific frequencies since they come up short on the security gave by the red and dark colored shades.  At the point when white-looked at guys are crossed with red-peered toward females, all the F1 descendants have red eyes, demonstrating that the allele for white is latent. Intersection the red-looked at F1 guys and females creates a 3:1 F2 proportion of red-peered toward to white-looked at flies, yet all the white-looked at flies are guys.  XYY disorder is a hereditary condition where a male has an additional Y chromosome. Side effects are normally not many. They may incorporate being taller than normal, skin break out, and an expanded danger of learning problems.There are 47 chromosomes, rather than the standard 46, giving a 47,XYY karyotype.
