Question

Which of the following statements is not true of two genes that show 50% recombination frequency ?

• A. The genes may be on different chromosomes
• B. The genes are tightly linked
• C. The genes show independent assortment
• D. If the genes are present on the same chromosome, they undergo more than one crossovers in every meiosis.

Answer 1

Answer: (B)

The genes are tightly linked

The genes that are not tightly linked to each other do not show 50% of recombination frequency. Genetic linkage is the process in which genes are located close to each other on chromosomes are inherited together. When 2 genes are located far from each other or are located on different chromosomes have 50% of recombination rates.

So, option B is the correct answer.
