Both gametes, sperm and egg, are formed by meiosis which is a type of sexual reproduction. Male gametes, sperm, is slightly smaller and has a tadpole shape to it and also is very mobile and produced by tons, but female gametes, egg, are larger, less mobile, and there are not so many eggs as sperm.
the formation of male and female gametes involves meiosis. In spermatogenesis meiosis produce 4 sperm cells. In oogenesis, cytoplasm divides unequally & meiosis produce 3 polar bodies that do not survive and one egg cell.
the beginning of the two processes is similar, a germinal epithelial cell (spermatogonium-2n- or oogonium-2n) undergoes repeated cell divisions, then the resulting spermatogonia and oogonia undergo growth to form primary spermatocyte (2n) and primary oocyte (2n). that is where the similarity ends.
after that the primary oocyte undergoes meiosis I to form a secondary oocyte(n) and a first polar body is attached to it (n), the secondary oocyte contains most of the cytoplasm of the 2 cells . then it undergoes meiosis II to form an egg with a haploid number of chromosomes and 2 polar bodies attached to it, also haploid. one primary oocyte forms one egg.
the primary spermatocye would undergo meiosis I to form 2 secondary spermatocytes(n)
these 2 cells would undergo meiosis II to form 2 spermatids (n) each. spermatids then differentiate into sperms. each primary spermatocyte forms 4 sperms.
Male gamete formation produces 4 gametes that become 4 sperm.
Female gamete formation produces 1 gamete that becomes an ova. The 3 remaining cells lose all their cytoplasm to the single ovum and become polar bodies. Depending on the species the polar bodies can play a role in fertilization/pregnancy and in others they die.
In males, all four daughter cells produced by meiosis will become sperm cells. In females, only one of the four daughter cells produced by meiosis will become an ovum. The ovum gets most of the cytoplasm and the other three smaller cells are called polar bodies and will be reabsorbed.
Female gametes form to the right of the wall of chromosomes, where as the gametes in males form to the left and in the middle of the wall.
female gametes form to the right of the wall of chromosomes, whereas the gametes in males, form to the left and in the middle of the wall. they are similar in the sperm, but unalike in egg
Gamete formation in females is known as oogenesis and spermatogenesis in males. They both occur by meiosis.
The testes in males and the ovaries in females produce gametes.
Collectively they are called gametes. Separately they're called sperm in males and eggs in females.
Gametes are cells that each have half of the normal chromosomes of the individual they belong to. The reason for this is that during reproduction, the chromosomes in each of the gametes add together to create a full set of chromosomes. Each half a set of chromosomes comes from a different person, which is why sexual reproduction produces offspring with mixed and different traits than their parents. The gametes in males are sperm, and the gametes in females are ova(egg cells). I hope this helped out ;)
Meiosis is type of cell division in which haploid gametes are formed .In human males ,it produces 4 sperms from one cell while in females only one egg and 3 non functional polar bodies are formed from one cell .
No, reverse that. Females are born with every egg they will ever have. Males produce sperm cells from puberty until death, so long as disease or injury do not interfere.

the function of gonads is to produce the gametes in both males and females.

Hardly. In mammals, for instance, the sperm of males is dwarfed by the egg of the female.

That would be the Gonads.
males reproduce more gametes
Meiosis is type of cell division in which haploid gametes are formed .In human males ,it produces 4 sperms from one cell while in females only one egg and 3 non functional polar bodies are formed from one cell .
do males and females have different abilities when eatimating size
No, reverse that. Females are born with every egg they will ever have. Males produce sperm cells from puberty until death, so long as disease or injury do not interfere.
