WebSome of the experiments performed in Morgan’s laboratory indicated linkage because the genes did not assort independently. In Drosophila the normal fly has grey body and long wings. There are some recessive mutations due to which the body colour of the fly is black and the wings are underdeveloped or vestigeal. ADVERTISEMENTS: WebIn the experiment by Bateson and Punnett, which of the following observations suggested genetic linkage in the sweet pea a. A 9:3:3:1 ratio was observed in the F2 offspring.b.

WebApr 11, 2024 · A genetic linkage map is a graphical representation of the relative locations of genes on a chromosome. It shows the distance between genes, which is measured in units of recombination frequency or centimorgans (cm). The closer two genes are on a linkage map, the higher the likelihood that they will be inherited together. ravenswood studio apartments

WebIt has the following salient features: 1. Genes that show linkage are situated in the same chromosome. 2. Genes are arranged in a linear fashion in the chromosome i.e., linkage of genes is linear. 3. The distance between the linked genes is inversely proportional to the strength of linkage.
