Show Answer
Answer:
Correct Answer: D
Solution:
- Recombination is the most common mechanism of genetic variation in the population of a sexually reproducing organism. It involves the exchange of genetic material either between multiple chromosomes or between different regions of the same chromosome. This mechanism is generally mediated by homologous chromosomes, during meiosis, i.e. formation of gametes or germ cells.
