Sex-linked inheritance was discovered by

Mendel studied seven pairs of traits in pea plants,which allow for $21$ possible combinations. If you are told that one of these combinations does not show independent assortment in a subsequent study,what would be your reaction?

Frequency of recombination between gene pairs on the same chromosome as a measure of the distance between genes to map their position on the chromosome was used for the first time by

When is the Law of Independent Assortment not applicable to genes?

Mendel observed that some characters did not assort independently. Later researchers found it to be due to

Why did Morgan work with the fruit flies $(Drosophila \text{ } melanogaster)$?
