Question

If both the parents have 23 pairs of chromosomes how does the baby have 23 chromosomes

Answer 1

At the time of genetic material transfer, division occurs meiotically then half of the chromosomes from each parents are transferred to the offspring.

Answer 2

$\huge{\boxed{\sf{ANSWER}}}$

The question can be answered by taking in point the process of crossing between parents.

The male gamete of the father has 23 chromosome and the female gamete of the mother has 23 chromosomes , so when both the male and female gamete fuses with each other during crossing, the zygote is formed which is diploid.

The zygote then undergoes meiosis division in which the zygote is turned into haploid nature.

The haploid zygote then turns into embryo and then to foetus and finally form a fully developed baby.

Thus, the baby gets 23 chromosomes (haploid).
