Question

The chromosomal number of the sexually producing parents and their offspring is the same. Justify this statement.

Answer 1

The first step in sexual reproduction is gamete formation. In this step, the number of chromosomes gets halved. Thus, each gamete receives half the number of chromosomes to that of somatic cells. During fertilisation, the fusion of male and female gametes takes place, which results in the number of chromosomes in the zygote to be equal to that of somatic cells. Thus, the chromosomal number of the sexually producing parents and their offspring is the same.

Answer 2

As for an individual a father has 23 pair of chromosomes and mother has 23 pair of chromosomes

So even in child they has same pairs and also in same no.
