Sex comprises the arrangements that enable sexual reproduction, and has evolved alongside the reproduction system, starting with similar gametes (isogamy) and progressing to systems that have different gamete types, such as those involving a large female gamete (ovum) and a small male gamete (sperm).In complex organisms, the sex organs are the parts that are involved in the production and exchange of gametes in sexual reproduction.

These gametes are the cells that are prepared for the sexual reproduction of the organism.

For instance, mate choice and sexual selection can accelerate the evolution of physical differences between the sexes.

One of the basic properties of life is reproduction, the capacity to generate new individuals, and sex is an aspect of this process.

This double-chromosome stage is called "diploid", while the single-chromosome stage is "haploid".

Diploid organisms can, in turn, form haploid cells (gametes) that randomly contain one of each of the chromosome pairs, via meiosis.Sexual reproduction in eukaryotes is a process whereby organisms form offspring that combine genetic traits from both parents.
