Answer:
The correct answer is: It increases genetic variation in offspring.
Step-by-step explanation:
Crossing over is a process that occurs during meiosis in which homologous chromosomes exchange genetic material. This exchange of genetic material between chromosomes creates new combinations of alleles that were not present in either parent. This increased genetic variation in offspring is beneficial because it can result in individuals with new and possibly advantageous traits that can increase their chances of survival and reproduction.
