The tendency of genes to remain together during the process of inheritance is known as

Genes $A$ and $B$ are linked. What will be the genotypes of the offspring produced from a cross between $AB/ab$ and $ab/ab$?

Distinguish between: Linkage in Sweet Pea and Linkage in Drosophila.

Which traits did Morgan choose for the male and female $Drosophila$ respectively to explain linkage and recombination?

In a fruit fly,the $X$-chromosome linkage map has a total length of $66$ units,with the yellow body gene $(y)$ at one end and the bobbed hair gene $(b)$ at the other end. What will be the recombination frequency between these two genes $(y$ and $b)$?

What map unit (Centimorgan) is adopted in the construction of genetic maps?
