How do Organisms Reproduce?

Short Answer Type

Explain how, offspring and parents of organisms reproducing sexually have the same number of chromosomes?

Sexual reproduction involves gamete formation. Number of chromosomes is halved during gamete formation. As a result, when two gametes fuse during fertilization, the number of chromosomes in zygote becomes same as in somatic cell of the organism. This ensures that offsprings produced by sexual reproduction have the same number of chromosomes as their parents.
