Question

Which of the following is an advantage of meiosis and sexual reproduction?

A. Meiosis ensures that offspring will not inherit any genetic disorders.
B. Meiosis ensures that offspring are genetically identical as their parents.
C. Meiosis ensures that offspring will have identical phenotypes to their parents.
D. Meiosis ensures a wider variety of genetic variation.

Answer 1

D. Meiosis ensures a wider variety of genetic variation.

This happens above all thanks to the Crossing over, the process in which the exchange of genetic material during sexual reproduction between two homologous chromosomes' non-sister chromatids results in recombinant chromosomes.
