Question

How is the chromosome number maintained in sexually reproducing organisms?

Answer 1

In sexually reproducing organisms. The chromosome number is maintained by the process of meiosis, in which the chromosome number is reduced to half, which is restored on fertilization.

Answer 2

Sexual reproduction is better than asexual reproduction. It involves fusion of two different gametes from two parents. This leads to new combinations of genes and genetic variation. Genetic variation helps offspring adapt to changing environments. It is essential for evolution and survival of species. Asexual reproduction produces genetically identical offspring, limiting adaptability.
