Question

State whether the following statement is true or false.

The limit of recombination is 50%.

Answer 1

This statement is true.

Explanation:

The maximum recombination frequency between two genes is 50%, which occurs when the genes are either on different chromosomes or very far apart on the same chromosome such that crossing over between them becomes independent. This 50% limit reflects the fact that recombination events cannot produce more than half recombinant gametes in a test cross because recombination between linked genes can only shuffle alleles up to this maximum frequency. Thus, recombination frequencies greater than 50% indicate independent assortment rather than linkage.
