Question

Determination of percentage of crossing over between two linked genes is important in __________.

• A. Maintaining heterozygosity in population
• B. Indicating relative position of genes in chromosomes
• C. Fixation of heterosis in organisms
• D. Explaining the phenomenon of coupling and repulsion

Answer 1

The correct option is B Indicating relative position of genes in chromosomes

If the distance between two linked genes is more then the frequency of crossing over will be more and vice versa.

Hence, percentage of crossing over may indicate the relative position of genes in chromosomes.

So, the correct answer is 'Indicating the relative position of genes in chromosomes'.
