Reproduction is a very important process necessary for the continuation of the progeny. Sexual and asexual reproductions are the two different types of methods by which plants and animals reproduce. Asexual reproduction is the form of reproduction in which young ones are born from a single parent. In sexual reproduction, both the male and the female gametes unite to form offspring. Mitosis and meiosis are the two important steps of cell division that lead to formation of new life.
Meiosis is a special type of reproduction which is used by humans, animals and certain plants. Meiosis occurs in two different stages, meiosis 1 and meiosis 2. In human males, meiosis occurs in the seminiferous tubules of the testicles while in females, it occurs in cells called as oogonia. In males, meiosis occurs at puberty while in females it occurs right at birth. The retinoic acid formed by the primitive kidneys stimulates the process of meiosis in females at birth, but in males this formation of retinoic acid is suppressed till puberty by the tissues of the testis. This suppression is overcome when at puberty the sertoli cells start producing retinoic acid on their own. This is a very important difference in the steps of meiosis in males and females.
The female gamete is produced inside the embryo sac of the ovule. Meiosis is a central feature of gametogenesis, but the adaptive function of meiosis is currently a matter of debate. A key event during meiosis is the pairing of homologous chromosomes and recombination (exchange of genetic information) between homologous chromosomes. Female And Male Gamete Cells: Called Sex Cells The Function of Gametes. Let’s take a look at the similarities between male. Most of the cells within the human body, as well as the bodies of other animals. When both female and male gametes merge the process is referred. Meiosis is the type of cell division that produces both male and female gametes. Spermatogenesis is the production of male gametes, and oogenesis is the production of female gametes. For both types of gametes, meiosis serves to halve the number of chromosomes so that upon fertilization the offspring has the requisite number of chromosomes. What Is the Difference Between Male and Female Gametes? Male gametes, or sperm, are small and motile while female gametes, or eggs, are larger and stationary. Males produce many more gametes in a lifetime than do females. Formation of the Female Gamete. There are a lot of phases and processes that occur during meiosis, but there are two main stages: meiosis I and meiosis II. At the end of meiosis I, two cells result, each with a full set of chromosomes. These cells again go through a process of duplicating and splitting, but this time.
In meiosis 1, there is splitting of the gametes into two in such a way that there is reduction in the number of chromosomes to half of what is present originally in parent cell. Initially, there is crossing over of chromosomes derived from the parent cells which helps in mixing the characteristics from each parent, and then half of the total chromosomes get distinctly separated from the other. All the chromosomes get equally distributed in halves; hence, they also carry traits of their parent cells in equal proportion. This step is also called as ‘reductional division’ as during the process of division, chromosomes reduce to half the number than originally present. Next step is meiosis 2; in this stage there is internal splitting of one half of the daughter cells and what we get is four daughter cells with different permutation and combination of the chromosomes.
Meiosis is important in mammals because when the male and the female gametes fuse to form the zygote, then during the formation of the zygote there is replacement of the lost number of chromosomes to restore the number to the original 42 chromosomes. If during meiosis 1 or meiosis 2, there is an error during division, such that there is an extra chromosome or one chromosome less, then it is termed as non-disjunction. If there is non-disjunction, then it will lead to formation of zygotes with extra chromosomes and will lead to the birth of a child with many anomalies or even mental retardation. Therefore, meiosis is a very important step in reproduction. The daughter cells formed by female gametes carry only the X sex chromosome while the daughter cells formed by male gametes carry either an X or Y sex chromosomes. As a matter of fact, meiosis is important for formation of the zygote but once the zygote is formed it grows further to become a fetus by mitotic cell division. Mitosis is plain replication of the cells by keeping the chromosome number intact as the parent cells.
Summary: Meiosis occurs at birth in females in oogonia cells but occurs at puberty in males in the seminiferous tubules. Meiosis is a process of cell replication where there is reduction of the number of chromosomes to half from the original.

Male gamete formation produces 4 gametes that become 4sperm.
Female gamete formation produces 1 gamete that becomes an ova.The 3 remaining cells lose all their cytoplasm to the single ovumand become polar bodies. Depending on the species the polar bodiescan play a role in fertilization/pregnancy and in others theydie.
What is the difference gamete formation in male animals from the gamate in female animals?
The difference is that the name is different and some animals are different. Like the lion the male ones have fur around its head and the female ones have nothing. 2. The difference is that the gamete in men produces 4 sperm, and in the female it makes 4 as well, but only 1 is used.
What are the difference between the Gamete and the Gonads?
gamete is a male and a female reproductive cell sperm and ovum. gonad is produce sex cells and hormones
What is the difference between a gamete and a spore?
gamete- a sex cell with half the total chromozomes which needs to meet another gamete to start a life spore- asexual reproduction unit with has a full set of cromozomes and can germinate to become a normal being, usually it is more hardy and is used to survive harsh conditions like winter or summer The difference between a gamete and a spore : - a gamete can be either a gamete male, or a gamete…
Differentiate gamete formation in male animals from gamete formation in female animals?
Male produces 4 surviving haploid gametes sperms where as female also produces 4 gamete haploid eggs of which 1 haploid survives and rest 3 become non-functioning polar bodies.........have fun guys
What is the difference between a polar body and an egg?
A polar body is a non-functional female gamete, because it is far too small to function properly. An egg is the one female gamete produced by meiosis that is large enough to fuction.

What is an ovum?
An ovum is an egg in the ovary of the female. This egg is called the female 'gamete' or sex cell. It combines with the male gamete, called a sperm, to form a zygote. This formation process is called 'fertilization.'

Why the female gamete bigger than male gamete?
I personally think that there are several reasons for this: 1. During sexual intercourse, it is the male gamete which travels towards the female gamete, thus it is obvious that the male gamete has to be smaller than the female gamete. 2. There is normally only one female gamete present during a particular sexual intercourse compared to millions of male gametes. So as not to make wastage, the male gamete is smaller than the female…
