Among humans and other mammals, males typically carry XY chromosomes, whereas females typically carry XX chromosomes, which are a part of the XY sex-determination system.Other animals have a sex-determination system as well, such as the ZW sex-determination system in birds, and the X0 sex-determination system in insects.

The defining characteristic of sexual reproduction in eukaryotes is the difference between the gametes and the binary nature of fertilization.

Disregarding intermediates, the basic distinction between asexual and sexual reproduction is the way in which the genetic material is processed.

Typically, prior to an asexual division, a cell duplicates its genetic information content, and then divides. In sexual reproduction, there are special kinds of cells that divide without prior duplication of its genetic material, in a process named meiosis.

Many species, particularly animals, have sexual specialization, and their populations are divided into male and female individuals.

Conversely, there are also species in which there is no sexual specialization, and the same individuals both contain masculine and feminine reproductive organs, and they are called hermaphrodites. The reason for the evolution of sex, and the reason(s) it has survived to the present, are still matters of debate.

As sexual reproduction developed by way of a long process of evolution, intermediates exist.

Bacteria, for instance, reproduce asexually, but undergo a process by which a part of the genetic material of an individual (donor) is transferred to an other (recipient).

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.

Some of the many plausible theories include: that sex creates variation among offspring, sex helps in the spread of advantageous traits, that sex helps in the removal of disadvantageous traits, and that sex facilitates repair of germ-line DNA.

Sexual reproduction is a process specific to eukaryotes, organisms whose cells contain a nucleus and mitochondria.

This mode of reproduction is called asexual, and it is still used by many species, particularly unicellular, but it is also very common in multicellular organisms.
