Detailed explanation-1: -The formation of sex cells is a central part of human reproduction: In fertilization, an egg cell and a sperm cell combine. These sex cells are also called reproductive cells or gametes.

Detailed explanation-2: -Humans are diploid, and most of the body’s cells contain 23 chromosomes pairs. Human gametes (egg and sperm cells), however, contain a single set of chromosomes and are said to be haploid.

Detailed explanation-3: -Sexually reproducing organisms are diploid (having two sets of chromosomes, one from each parent). In humans, only the egg and sperm cells are haploid.

Detailed explanation-4: -A gamete (/ˈɡæmiːt/; from Ancient Greek (gametḗ) ‘wife’, ultimately from Ancient Greek (gámos) ‘marriage’) is a haploid cell that fuses with another haploid cell during fertilization in organisms that reproduce sexually. Gametes are an organism’s reproductive cells, also referred to as sex cells.

Detailed explanation-5: -When a sperm fuses with an egg, the two combine to produce a new cell, called a zygote. This is the first step in the development of a new organism.” zygote: A cell that forms when two gametes fuse. in humans, those gametes are an egg and sperm.
