What does gametogenesis in male animals result in?

Gametogenesis occurs when a haploid cell (n) is formed from a diploid cell (2n) through meiosis. We call gametogenesis in the male spermatogenesis and it produces spermatozoa. In the female, we call it oogenesis. It results in the formation of ova.

What is the result of gametogenesis in males?

During male gametogenesis, the haploid microspore undergoes a mitosis to form a vegetative and a generative cell. A second mitotic division of the generative cell results in the formation of two sperms. The vegetative and sperm cells are enclosed in the pollen coat (reviewed by Mascarenhas, 1989).

How is gametogenesis different in males and females?

The main difference between male and female gametogenesis is that in animals, male gametogenesis or spermatogenesis is responsible for the production of sperm cells from the male germ cells called spermatogonia, whereas female gametogenesis or oogenesis is responsible for the production of egg cells from female germ ...

Where does gametogenesis occur in males?

Male Gametogenesis (Spermatogenesis)

Primordial germ cells (46,2N) migrate into the testes at week 4 of development and remain dormant. At puberty, primordial germ cells differentiate into type A spermatogonia (46,2N).

What are produced during gametogenesis?

Gametogenesis, the production of sperm and eggs, takes place through the process of meiosis. ... Meiosis produces haploid cells with half of each pair of chromosomes normally found in diploid cells. The production of sperm is called spermatogenesis and the production of eggs is called oogenesis.

Does gametogenesis occur in animals?

In animals, gametogenesis occurs in the reproductive organs via meiosis. In humans, each sex cell is haploid, which combine to form a diploid zygote with 23 pairs or 46 total chromosomes, of which 44 are autosomes that code for traits not sex-related.

What is gametogenesis explain?

gametogenesis, in embryology, the process by which gametes, or germ cells, are produced in an organism. The formation of egg cells, or ova, is technically called oogenesis, and the formation of sperm cells, or spermatozoa, is called spermatogenesis.

How does gametogenesis contribute in genetic diversification?

Crossing Over

During prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.

What is gametogenesis and fertilization?

Genetically and functionally competent gametes are a prerequisite for normal fertilization and early embryo development. The first phase in the sexual reproduction of an organism is gametogenesis, a process of formation of gametes from the germ cells in the testes and ovaries.

How does gametogenesis differ in plants and in animals?

The major difference between gametogenesis in animals and plants is that in animals it includes the transformation of the cells from diploid cells to haploid cells and the formation of haploid gametes; and in plants gametogenesis is the formation of the gametes from haploid cells.

What is male gametogenesis describe male gametogenesis in plants?

Gametogenesis is a biological process by which haploid male and female gametes are formed. This occurs in both plants and animals. Sporogenesis is the formation of spores whereas gametogenesis is the formation of gametes. ...

What is Homogametes?

Homogametes are those gametes which bear morphological and anatomical resemblance with each other. ... The male gamete in humans is known as the sperm while the female gamete is known as the ovum or the egg. This sperm fertilizes the ovum to form a zygote which further develops into an embryo.

Why does gametogenesis occur in males and females?

Gametogenesis: The development and production of the male and female germ cells required to form a new individual. The male and female germ cells are called gametes. ... After sexual intercourse, an ejaculated sperm cell penetrates an egg and unites with it (fertilizes it).

What hormones are involved in gametogenesis?

FSH acts on the gamete-producing cells to regulate gametogenesis. LH acts on the endocrine or hormone-producing cells, stimulating release of steroid sex hormones.

How gametogenesis maintain the chromosome number?

During gametogenesis or fertilization each gamete carries haploid sets of chromosomes (23 pairs). When these gametes fuses, the set of chromosome becomes diploid (46 pairs). ... This is how number of chromosomes is maintained from one generation to another.

How does gamete formation differ in plants?

Plants which reproduce sexually also produce gametes. However, since plants have a life cycle involving alternation of diploid and haploid generations some differences exist. Plants use meiosis to produce spores that develop into multicellular haploid gametophytes which produce gametes by mitosis.
