Concept in Definition ABC

The word gamete is a very present term and mentioned within the scope of thebiologyand especially within the context of reproduction human, vegetable or animal, since it designates the cell male or female, sperm or ovum, respectively, responsible and specialized in reproduction.

It should be noted that gametes are haploid sex cells, because they contain a single set of chromosomes, or in their defect half the normal number of chromosomes in diploid cells (two sets of chromosomes), which, generated by meiosis from diploid cells.

If it is a woman, the gamete is called an ovum, on the other hand, if it is a man we speak of sperm. When both gametes, male and female, merge, generate a cell known as zygote or fertilized egg which will contain two sets of chromosomes (diploid cell).

Gamete conformation through meiosis is formally designated as gametogenesis. In this process the number of chromosomes existing in the germ cells will be reduced from diploid to haploid, that is, from double to single and to half the number of chromosomes that a normal cell of the

species in question.

Meanwhile, they are specific organs, gonads in animals and gametangia in vegetables , those specialized when it comes to producing gametes.

At the behest of animals the gametes result from the germ line, a root mobile very specific that will differ in the early stages of development.

On mushrooms or protists It happens that the gametes are identical in shape and appearance but in evolution They can be distinguished because the male is smaller and more mobile with respect to the female, which is larger and immobile.
