the process by which gametes are produced in female animals

Meaning of Gametogenesis

What is Gametogenesis:

Gametogenesis is the process by whi certain organisms, su as humans and some ants, begin the process of cell division for the formation of gametes or sexual cells.

In biology, gametogenesis is observed in humans, animals and ants, the process by which gametes are produced in female animals. The process begins with the division of dioid germ cells to form gametes (haoid cells).

In this way, ea living being has different biological cycles that define the quantity, form and moment in whi gametogenesis will be activated, but all of them are aracterized by their sexual reproduction.

Gametogenesis occurs in the germ cells, whi contain the genetic information. A dioid germ cell, that is, containing only half of the genetic information in a set of romosomes, divides in meiosis to generate 4 haoid cells or gametes.

In this way, gametogenesis allows gametes, both male and female, to contain only half of the genetic information, thus generating genetic diversity with the genes of the mother and father.

Human gametogenesis

Gametogenesis in humans is different for the formation of male and female gametes. It is for this reason that male gametogenesis is called spermatogenesis and female gametogenesis is called oogenesis.

Gametogenesis and oogenesis

Female gametogenesis, or also known as oogenesis, refers to the meiosis of dioid cells that give rise to the formation of oocytes or female gametes. Oogenesis in humans takes approximately 28 days and they are deposited in the ovaries.

Gametogenesis and spermatogenesis

In male gametogenesis or spermatogenesis dioid cells undergo meiosis to give rise to the formation of spermatozoa or male gametes. In humans, this process takes approximately 74 days and they are stored in the testicles.

Gametogenesis and fertilization

Gametogenesis is the process by whi sex cells are formed. In this sense, the fertilization would not be possible without gametogenesis.

From the opposite point of view, it is in fertilization that the comete genetic material is determined, whi will define in due time whether gametogenesis will be female or male.

Gametogenesis and meiosis

The meiosis ays a fundamental role in gametogenesis, since it is the process of cell division that allows a dioid cell to be divide into haoid cells, also known as sex cells.

Gametogenesis in ants

Gametogenesis is generated in the so-called higher ants that reproduce sexually.

Plants generate, through meiosis, the division of dioid cells to form male and female gametes. The female gametes or ovules are located in the embryo sac of the flowers, waiting to be fertilized by male gametes, generally in the form of pollen.

Which type of transformer used in arc welding
Introduction to Arc Welding The tenique of electric arc welding consists of melting a metal at a high temperature by using a potential differential and a determined electric current intensity value. Through this potential difference, the air is ionized and the electrons are transported through the electrodes and the piece to weld, which type of transformer used in arc welding.
