Question

Describe how linkage and Recombination is calculated? Detail answer please. ​

Answer 1

Answer:

Thomas Hunt Morgan worked on Drosophila melanogaster (fruit flies) to explain how the process of sexual reproduction produced variations. He preferred to work on fruit flies or Drosophila melanogaster for the subsequent reasons:

It could be cultivated easily on a synthetic medium in the laboratory.

Exhibit a short lifespan (two weeks).

A single mating could generate multiple progenies.

Differentiable male and female sexes.

Hereditary variations are of different types.

Morgan carried out a dihybrid cross between white-eyed and yellow-bodied females and red-eyed and brown-bodied males. Self-crossing of the F1 generation surprisingly produced an F2 generation without being the ratio of 9:3:3:1. The outcome exhibited a divergence from Mendel’s dihybrid cross in peas.
