Distance between the genes and percentage of recombination shows:
A. a direct relationship
B. an inverse relationship
C. a parallel relationship
D. no relationship
Distance between the genes and percentage of recombination shows a direct relationship. When genes are tightly linked they show low recombination. So as distance between genes increases the percentage of recombination increases hence they having a direct relationship.
Recombination describes the non parental gene combinations. The crossing over taking place during meiosis in which non sister chromatids cross over results in non parental combination. This recombination is due to the “distance between genes”which allow them to get separated during crossing over.
