Overview The male gamete sperm fertilizing the female gamete ovum One of the basic properties of life is reproduction, the capacity to generate new individuals, and sex is an aspect of this process. Life has evolved from simple stages to more complex ones, and so have the reproduction mechanisms.

Initially the reproduction was a replicating process that consists in producing new individuals that contain the same genetic information as the original or parent individual. 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, including many of those with sexual reproduction.

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 another recipient.

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

The resulting cells are called gametesand contain only half the genetic material of the parent cells.

These gametes are the cells that are prepared for the sexual reproduction of the organism. Many species, both plants and 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. This is very frequent in plants. Evolution of sexual reproduction Different forms of anisogamy: A anisogamy of motile cells, B oogamy egg cell and sperm cellC anisogamy of non-motile cells egg cell and spermatia.

Different forms of isogamy: A isogamy of motile cellsB isogamy of non-motile cells, C conjugation. Sexual reproduction first probably evolved about a billion years ago within ancestral single-celled eukaryotes. Some of the many plausible theories include: Sexual reproduction is a process specific to eukaryotesorganisms whose cells contain a nucleus and mitochondria.

In addition to animals, plants, and fungi, other eukaryotes e. Some bacteria use conjugation to transfer genetic material between cells; while not the same as sexual reproduction, this also results in the mixture of genetic traits.

The defining characteristic of sexual reproduction in eukaryotes is the difference between the gametes and the binary nature of fertilization. Multiplicity of gamete types within a species would still be considered a form of sexual reproduction. However, no third gamete type is known in multicellular plants or animals.

The ZW sex-determination system is shared by birds, some fish and some crustaceans. XY sex determination is used by most mammals, [14] but also some insects, [15] and plants Silene latifolia.

A paper from compared the chicken Z chromosome with platypus X chromosomes and suggested that the two systems are related. Isogamy and Anisogamy The life cycle of sexually reproducing organisms cycles through haploid and diploid stages Sexual reproduction in eukaryotes is a process whereby organisms form offspring that combine genetic traits from both parents.

Chromosomes are passed on from one generation to the next in this process. Each cell in the offspring has half the chromosomes of the mother and half of the father. 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.

Crossing over and fertilization the recombining of single sets of chromosomes to make a new diploid result in the new organism containing a different set of genetic traits from either parent.I recently read at a convention a piece of fiction with a male protagonist written in the first person.

Afterwards, one of the male audience members came up and asked me how I managed to write a character of the opposite gender so realistically.
