The scientists who proposed the theory of linkage are

Linkage decreases the frequency of

In female $Drosophila$,linked genes show recombination during meiosis. However,such recombination does not occur during sperm formation in male $Drosophila$. Why?

Gene-mapping technology was developed by

The chromosome maps are not accurate maps because

What was the phenotypic ratio obtained in the experiment on linkage and recombination performed in Lathyrus odoratus (Sweet Pea)?
