All of them
Tetrads form during meiosis. Tetrad refers to the four chromatids of homologous chromosomes.These are present during Prophase.
46 chromosomes..

Meiosis is known as a reduction division. The total number of chromosomes present prior to meiosis is reduced in half at the end of meiosis. In this case 12 pairs of chromosomes before meiosis (a total of 24 chromosomes) becomes 12 chromosomes (one of each pair) at the end of meiosis.

In humans, 46 chromosomes are present when meiosis begins. The four daughter cells that result from meiosis have 23 chromosomes.

There are many differences between meiosis and mitosis, and it can all be summed up by understanding they have different functions in life processes. Mitosis is all about creating cells that are identical to each other asexually. This provides multi-cellularity in multicellular beings. Meiosis, on the other hand, is all about the production of gametes (sex cells) from a single germ cell in order to make sexual reproduction possible. Taking all of this into considering, Mitosis is seen as being a part of a cyclical cell life cycle, so it happens more than once. Meiosis is a process that happens only once for a germ cell largely because it is a process that creates haploid cells from diploid cells. Note that because of these differences Mitosis requires the replication of DNA to occur in order for diploid cells to create more diploid cells. Diploid meaning that a full set of chromosomes are present; human diploid cells would have 46 chromosomes, 23 from the mother and 23 from the father that are paired up with each other. Haploid, would mean 23 human chromosomes in total; with regards to Meiosis, the chromosomes would be a combination of the genes that an individual inherited from his or her parents. In Meiosis, which is divided into two parts, replication of DNA occurs before Meiosis I is carried out, but no replication occurs before proceeding to Meiosis II in order to achieve creating haploid cells.
Meiosis? that is when one haploid cell devides into two diploid (gamete) cells, right? Whereas mitosis is complete cell repulation. Hence, I'd say the difference is that DNA synthesis (two lots of DNA) are present in mitosis, whereas the genetic information is split in meiosis. - hence 23 chromosomes in a gamete, not 46.
both will have 30 chromosomes.
