Question

Which of the following is correct for the effect of linkage on recombination?

It increases the percentage of recombinants.
It results in 50% recombinants.
It reduces the percentage of recombinants.

Answer 1

It reduces the percentage of recombinants.

Step-by-step explanation:

The independent assortment of genes gives rise to new gene combination and recombinants. Linkage refers to the tendency of two genes present in the vicinity on the same chromosome to get transmitted together.

Since the linked genes are inherited together, they do not exhibit independent assortment. Due to the absence of independent assortment in linked genes, more of parental types and lesser recombinants are formed.

Answer 2

The answer for your following question would be : C. It reduces the percentage of  recombinants. From the following options, The one that is correct for the effect of linkage on recombination is : it reduces the percentage of recombinants
