Where in humans would you expect to find meiosis taking place?

The cells that would be made are sex cells (germ cells), so for males it would be sperm and the hormone testosteron in the testes,and for women it would be eggs and the hormone estrogen in the ovaries.


What are the types of cells in which you would expect synapsis to occur?

Cells that are beginning to divide by meiosis.Synapsis is the pairing and aligning of two homologous chromosomes. This only occurs in prophase I of meiosis.Just what type of cell is dividing by meiosis depends on the species. In humans the answer would be cells that are forming gametes (oocytes and spermatocytes). In plants meiosis always produces spores; gametes are formed by mitosis.


What would happen if crossing over didn't happen during meiosis in humans?

There would be less genetic variation in humans


What would happen if crossing over in meiosis didn't happen in humans?

If crossing over didn't happen during meiosis in humans, the haploid daughter cells would all have the same genes. The crossing over creates variation and causes each daughter cell to have slightly different genes.

Why does a mitosis performing cell changes himself to perform meiosis?

Meiosis occurs in only the reproductive cells to form gametes (in humans... eggs and sperm). And it would be performed to perpetuate a species...

How many chromosomes are at the end of meiosis II?

A diploid organism have: 2n chromosome after meiosis 1, the gametes would still have 2n as DNA replication occured Meiosis 1 can be assumed to be the same process as Mitosis. after meiosis 2, the gametes would have n (1/2 of 2n), as the second meiosis would not include any form of DNA replication.


How would you expect humans to use land in region of plains?

i would expect people to do lots of farming


How many chromosos are in each cell after meiosis?

After meiosis is complete, each resulting cell typically contains half the number of chromosomes as the original cell. This means that in humans, each cell after meiosis would have 23 chromosomes, as opposed to the usual 46 chromosomes in a somatic cell.


What do Meiosis I and Meiosis II have in common?

Both Meiosis I and Meiosis II involve the processes of prophase, metaphase, anaphase, and telophase. Additionally, both stages result in the formation of haploid cells with half the number of chromosomes as the original cell.


Why do sexual reproductiong organism needs both mitosis and meiosis?

Meiosis is also termed as reduction division. first the diploid(2n) gamete undergoes meiosis to become haploid(1n) then fertilization takes place. For growth and development mitosis is necessary. Meiosis is needed to half the chromosomes number . For example in human there are 46 chromosomes. if fertilization takes place without meiosis then the resulting organism would have 92 chromosomes which off course will not be a human!
