How does crossing over during meiosis affect the genetic variability of the resulting offspring?A.

Question

It does not change genetic variability because all the genes

B. It does not change genetic variability because environmental changes affect variability. are still the same.
C. It increases genetic variability due to mixing of the genetic material between chromosomes.
D.
It decreases genetic variability because there are fewer surviving offspring due to mutations.

Answer 1

The correct answer is: C. It increases genetic variability due to mixing of the genetic material between chromosomes.

Crossing over during meiosis is the process where homologous chromosomes exchange segments of their genetic material. This results in new combinations of alleles, which increases the genetic variability of the gametes produced. When fertilization occurs, the resulting offspring have a unique combination of genes, leading to greater genetic diversity within a population.
