The process of forming gametes (sperm and egg cells).

The union of a sperm and an ovum, resulting in a single cell.

Gamete cells contain half the number of chromosomes as a somatic cell.

A zygote has a full set of chromosomes, half from each gamete.

The process resulting in gamete formation is called meiosis, a type of cell division that reduces the chromosome number by half.
Meiosis produces four non-identical haploid cells, crucial for sexual reproduction.

Upon fertilization, the ovum (egg) is joined by a sperm, forming a single cell called a zygote.
This process restores the diploid chromosome number, combining genetic material from both parents.

Gamete cells, which are haploid, contain 23 chromosomes in humans.
The zygote, as a diploid cell, contains 46 chromosomes, inheriting 23 from each parent.

The defined development process that the zygote undergoes is known as embryogenesis.
This period involves rapid cell division and differentiation, leading to the formation of tissues and organs as the embryo develops.
