Answer 2

(Question based on: GENETICS)

$\LARGE{\underline{\boxed{\bf{\blue{Required\:Answer:}}}}}$

A normal human cell is diploid whuch means it have 23 pair of chromosomes i.e. 46 chromosomes. Out of these:

• 22 pairs (44) are autosomes.
• 1 pair (2) is a sex chromosome.

But a sex cell/gamete is haploid which means, it have 23 chromosomes (not in pairs!). It is having only one set of chromosome out of the pair$.$

These haploid pairs fuse to form the zygote (after fertilization). Thus, the correct option is Option A (23)

• The normal human cell or non-reproductive cells is known as somatic cells.

• The gametes are formed as a result of meosis, hence the no. of chromosomes reduced to half.
