How do the daughter cells after meiosis compare to the parent cell?

Answer 1

1. primary spermatocyte (dipolotid (46))

------1st meiotic division------

produce: 2 secondary spermatocytes (haploid (23))

------2nd meiotic division--------

Producing four spermatids (haploid (23))

so the difference is that in the begnning u have a dipoloid cell with 46 chromosomes, and in the end u wil have a haploid cell with 23 chromosomes that in the case are ready to meet the egg, and produce a zygote (diplotid, with 46 chromosomes) that wil develop to be a child.

Answer 2

At the beginning of meiosis (just like the beginning of mitosis) a cell contains 2N chromosomes (all of which are identical to the parent organism) where each chromasome consists of 2 sister chromatids bonded together at their middle called a centromere. In humans the value of N is 23, meaning they start with 46 chromosomes and 92 chromatids, but other creatures will have different numbers.

Before separating the chromosomes, genetic material is crossed over between homologous chromosomes, ensuring that all chromosomes are now unique. By the end of Meiosis I, the homologous chromosomes have split into 2 different cells each with N chromosomes, but each chromosome still has 2 chromatids. In meiosis II, each new cell splits the chromosome in half, giving half of their chromatids to a new cell. The end result are 4 haploid cells with N chromosomes each consisting of 1 chromatid, with the chromatids different between each of the 4 (and every 4 ever produced).

In females, the process is a little different. At the end of Meiosis I, the cytoplasm is unevenly distributed, so that there is a large secondary oocyte and a smaller polar body. At the end of Meiosis II, the oocyte splits into a large mature ovum and a small polar body, while the polar body from Meiosis I splits into 2 new even smaller polar bodies. All of these final cells still have N chromosomes with 1 chromatid each.

Answer 3

The process of nuclear division called meiosis results in to four haploid cells from a diploid mother cell. All the 4 haploid cells thus formed are similar in their make up and number of chromosomes normally, but their genetic make up is variable due to a process called crossing over.

Answer 4

They are non-identical and haploid. The parent cell is diploid.

Answer 5

The difference between the cells at the beginning and the end, is that the cell at the beginning is a body cell and the cells at the end are 4 sex cells.

Answer 6

at the end their are 2 daughtor cells
