Question

Distance between the genes and percentage of recombination shows

• A. a direct relationship
• B. an inverse relationship
• C. a reciprocal relationship
• D. no relationship

Answer 1

The correct option is A a direct relationship

When distance between two genes increase, chances of crossing over increase between the two genes present on non sister chromatids of homologous chromosome. Crossing over is directly porportional to the recombination. More the crossing over, more the chances of exchange of gene and more is the new recombination formed. Hence, distance between gene has a direct relationship with percentage of recombination.
