Solution

In asexually reproducing organisms, only one parent is involved. The part of the body which develops into a new organism contains cells having the same number of chromosomes as any other cell in the body of the organism. This separated part develops and forms a new organism. For example, human being somatic cells contain 46 chromosomes. When gametes are formed, they contain half the number i.e., 23 chromosomes but when gametes fuse to form the zygote, they maintain the 46 chromosomes. In sexually reproducing organisms, the parents are diploid (2N) as each of them is having 2 complete sets of chromosomes. They form haploid (N) male and female gametes by the process of meiosis. The haploid gamete has one set of chromosomes since, these gametes fuse during fertilisation and restore the original number of chromosomes in the offspring.
