How many chromosomes are present in the cell after meiosis II?
12
Meiosis II is similar to which process?
Meiosis II is identical to Mitosis. Meiosis is split into two stages, Meiosis I and Meiosis II. Meiosis I is similar to mitosis however the cells resulting from it have half as many chromosomes as the parent cell.
What division of meiosis splits chromosomes?
In anaphase I of meiosis, the homologous pairs of chromosomes separate. Due to DNA replication and crossing over during prophase I, these chromosomes consist of a pair of non-identical sister chromatids. During anaphase II of meiosis, the sister chromatids separate into individual chromosomes.
Difference between Meiosis 1 and 2?
In meiosis 1, the chromosomes were double strand while in meiosis 2, it is single strand.
Why does meiosis require two cellular divisions?
Meiosis is divided into Meiosis I and Meiosis II because the initial cell divides twice producing four genetically different sex cells (gametes) Each time a cell divides, it goes through Prophase, Metaphase, Anaphase, and Telophase. See the link below for a diagram showing the process.
How many cells form at the end of human meiosis and how many chromosomes do they each contain?
At the end of meiosis II, four haploid cells form. Haploid means they have only one set of chromosomes. For humans, that would be 23 chromosomes.
How many chromosomes are present in the cell after meiosis II?
12
How do metaphase of meiosis I and meiosis II differ?
It is different because pairs of chromosomes line up down the middle and in metaphase II single chromosomes are lined up across the middle
Are formed at the end of meiosis?
At the end of Meiosis II, Spermatids are formed
When do sister chromatid separate during meiosis?
The sister chromatid separate during anaphase II in meiosis. During anaphase I homologous chromosomes get separated.
Meiosis II is similar to which process?
Meiosis II is identical to Mitosis. Meiosis is split into two stages, Meiosis I and Meiosis II. Meiosis I is similar to mitosis however the cells resulting from it have half as many chromosomes as the parent cell.
What stage of meiosis is when chromosomes line up in the center of the cell?
Chromosomes line up in the middle of the cell during meiosis.
What Best describe meiosis?
Meiosis is a two-part cell division process in organisms that sexually reproduce. Meiosis produces gametes with one half the number of chromosomes as the parent cell. There are two stages of meiosis: meiosis I and meiosis II. At the end of the meiotic process, four daughter cells are produced. Each of the resulting daughter cells has one half of the number of chromosomes as the parent cell.
If a cell with 40 chromosomes undergoes mitosis each of the daughter cells will have chromosomes.?
Meiosis results in gametes that have half the number of chromosomes of other cells. A gamete carries one of each pair of homologous chromosomes. Their are 46 chromosoes in Meiosis I and 23 in Meiosis II.
What are the two distinct of meiosis?
I think what you are asking is "What are the two distinct processes of meiosis?"At the beginning of meiosis, there is a diploid cell (chromosomes come in pairs) with duplicated chromosomes (each pair of chromosomes is duplicated). The cell undergoes two processes: Meiosis I and Meiosis II.Meiosis I produces two haploid cells (unpaired chromosomes), but the chromosomes are still duplicated. These two cells then undergo Meiosis II, in which the two haploid cells are split, with one set of unpaired chromosomes going to one and the other set of unpaired chromosomes to the other. The end result of Meiosis II is four haploid cells with unduplicated chromosomes.In short, when a cell undergoes the complete process of meiosis, a single diploid cell with duplicated chromosomes is turned into four haploid cells with unduplicated chromosomes.For a complete description of all the steps along the way, see this page and scroll down about 2/3 of the way: http://en.wikibooks.org/wiki/Adventist_Youth_Honors_Answer_Book/Health_and_Science/Heredity

What is the change in chromosome number in meiosis?
The Reduction of Chromosome Number in Meiosis Is Determined by Properties Built into the Chromosomes. In meiosis I, two chromatids move to each spindle pole. Then, in meiosis II, the two are distributed, one to each future gamete. This requires that meiosis I chromosomes attach to the spindle differently than meiosis II chromosomes and that they regulate chromosome cohesion differently. We investigated whether the information that dictates the division type of the chromosome comes from the whole cell, the spindle, or the chromosome itself. Also, we determined when chromosomes can switch from meiosis I behavior to meiosis II behavior. We used a micromanipulation needle to fuse grasshopper spermatocytes in meiosis I to spermatocytes in meiosis II, and to move chromosomes from one spindle to the other. Chromosomes placed on spindles of a different meiotic division always behaved as they would have on their native spindle; e.g., a meiosis I chromosome attached to a meiosis II spindle in its normal fashion and sister chromatids moved together to the same spindle pole. We also showed that meiosis I chromosomes become competent meiosis II chromosomes in anaphase of meiosis I, but not before. The patterns for attachment to the spindle and regulation of cohesion are built into the chromosome itself. These results suggest that regulation of chromosome cohesion may be linked to differences in the arrangement of kinetochores in the two meiotic divisions.
