The primary spermatocyte is diploid(2n) and after first meiotic division it will produce 2 haploid(n) secondary spermatocyte and these in turn after second meiotic division will produce 2 more haploid secondary spermatocyte. Therefore by the end of Meiosis one will have 4 haploid secondary spermatocyte or spermatids.
Mitosis in humans usually results in the formation of 2 diploid cells.
four haploid gametes (a haploid gamete contains half the number of chromosomes then the somatic cells)
d. Four haploid gamete cells
four monoploid cells
In which structure or organ does meiosis formation of male gametes and or female gametes occur in plants male and females
Asexual reproduction in animals is usually by parthenogenisis. In such cases, the egg is usually produced without going through meiosis. The result may be female or male, depending on how sexuality is determined in the specific species. The species in which parthenogenisis has been observed include a variety of insects, fish, reptiles, birds and mammals. It can be induced artificially, and all cases observed in mammals have been artificial.
Meiosis produces haploid cells from a diploid cell
Meiosis occurs in the reproductive cells to form male and female gametes. For sexual reproduction meiosis is essential. Genetic advance is achieved by crossing over in chromosomes during meiosis, hence meiosis helps in evolution of races in plants.Meiosis occurs in the reproductive cells to form male and female gametes.

The formation of male gametes or sperm cells is called spermatogenesis. This is a form a meiosis, in which four daughter cells are formed. The process takes places in the male reproductive organs, the testes. The female counterpart to this is called oogenesis, which produces one usable daughter cells, an oocyte or egg cell, (and three discarded cells called polar bodies) this process occurs in the ovaries.
During sexual reprodution the egg and sperm undergoe meiosis, which would be i the female ovary. For more answers and elaboration, consult me, The New MrSpock (Xbox Live Gamertag).

Tetrads only appear in meiosis. The tetrad is the joining of four chromosomes in prophase I of meiosis. Two male duplicated chromosomes and two female chromosomes. The most important role of tetrad formation is ' crossing over. ' This is the exchange of genetic information between the male and female chromosomes. The material, whole genes, is physically swapped between the male and female chromosomes.
Well HELLO! why wouldn't they? Mammals have nipples.
They do not go through meiosis.
Secondary spermatocytes are formed at the end of Meiosis I and spermatids are formed at the end of Meiosis II.
parthenocarpic
Meiosis produces haploid cells from a diploid cell
Meiosis is the process that produces the sex cells.
