Question

Sex Linked inheritance: Set up your own mating between two flies but at least one parent must have a white allele in it, and present the Punnett square, genotype and phenotypes of both parents and the offspring of this cross. Remember to show the alleles on the X and/or Y chromosomes. W cannot be used for white and for the wild at the same time. Subscripts must be used. i.e X^w+Y  x  X^w+X^w

1 X^w+Y : 1 X^wY : 1 X^w+X^w+ : X^w+X^w

1 redeyed male : 1 whiteeyed male :2 red-eyed females

Answer 1

The Summary :- The phenotypic and genotypic ratio is calculated by punnett's square . The Ratio of genotypic ratio is 1:1:1:1 and Ratio of phenotypic ratio is 3:1 red eyed and white eyed respectively irrespective of the sex of the progeny.
