The presence of recombinants is due to.....

If $F_2$ of a dihybrid cross contains only parental combinations,then Mendel would have discovered .....

The frequency of recombination between gene pairs on the same chromosome as a measure of the distance between genes was explained by

When the number of recombinant progeny is usually less than the number expected in independent assortment, it is called:

Two genes '$a$' and '$b$' show $20\%$ recombination. What will be the proportion of gametes produced by a dihybrid $F_1$ individual with the genotype $++/ab$,derived from a cross between $++/++$ and $ab/ab$?

Linkage was first studied by .....
