Question

Which of the following events of meiosis creates genetic variation among the gametes?

a. crossing over
b. random separation of maternal and paternal chromosomes
c. distribution of differing numbers of chromosomes to daughter cells
d. Both a and b.
e. All of the above.

Answer 1

Crossing over is the event in meiosis that creates genetic variation among the gametes.

Step-by-step explanation:

The event of meiosis that creates genetic variation among the gametes is crossing over. Crossing over occurs during meiosis when chromosome pairs exchange DNA, leading to the creation of recombinant chromatids with new combinations of maternal and paternal genes. This process increases the variance of genetic combinations in the haploid gamete cells.
