chromosomes duplicate before mitosis
The Chromosome go through 5 phases:
1. Interphase - the cell's chromosomes duplicate. the nucleolus is clearly visible ion the nucleus.
2. Prophase - the chromatid pairs are now visible and the spindle is beginning to form.
3. Metaphase - chromatid pairs are lined up in the center of the cell.
4. Anaphase - the chromsomes have seperated.
5. Telophase - in the final step, the cytoplasm is beginning to seperate.
The 2 new cells that were created, enter interphase and cell division usually begins again.
The chromosomes are duplicated before mitosis begins.

How many chromosomes are present in the cell after meiosis II?
After meiosis II, each cell will have a haploid number of chromosomes, which means they will have half the number of chromosomes compared to the original cell before meiosis.
How many chromosomes would a cell have during metaphase 1 of meiosis if it has 12 chromosomes during interphase?
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.
The pairing of homologous chromosomes before nuclear division happens in what type of cell division?
The pairing of homologous chromosomes before nuclear division occurs in meiosis. Meiosis is a type of cell division that results in the formation of sex cells (sperm and egg cells) with half the number of chromosomes as the parent cell.
Does meiosis result in the doubling of chromosomes?
No, meiosis does not result in the doubling of chromosomes. Instead, it reduces the number of chromosomes in a cell by half.
What is the number of chromosomes in a meiosis parent cell?
A meiosis parent cell, also known as a germ cell, has a total of 46 chromosomes before undergoing the process of meiosis. During meiosis, the parent cell will divide and produce gametes with half the number of chromosomes, which is 23.

The pairing of homologous chromosomes before nuclear division occurs in meiosis. Meiosis is a type of cell division that results in the formation of sex cells (sperm and egg cells) with half the number of chromosomes as the parent cell.
What is the first thing chromosomes do in meiosis?
In meiosis, chromosomes replicate during interphase before the start of cell division. This process ensures that each daughter cell will receive the correct number of chromosomes.
Does meiosis result in the doubling of chromosomes?
No, meiosis does not result in the doubling of chromosomes. Instead, it reduces the number of chromosomes in a cell by half.
Does meiosis double the parental chromosomes number?
Meiosis 1
What is the number of chromosomes in a meiosis parent cell?
A meiosis parent cell, also known as a germ cell, has a total of 46 chromosomes before undergoing the process of meiosis. During meiosis, the parent cell will divide and produce gametes with half the number of chromosomes, which is 23.
How does the number of chromosomes in metaphase of mitosis compare to the number of duplicated chromosomes in metaphase 2 of meiosis?
In metaphase of mitosis, the number of chromosomes is equal to the number of duplicated chromosomes. However, in metaphase 2 of meiosis, the number of chromosomes is half that of the duplicated chromosomes, since meiosis involves two rounds of cell division to produce haploid cells.
How many chromosomes does a woman's cell have before undergoing meiosis?
A woman's cell has 46 chromosomes before undergoing meiosis, which is the process of cell division that produces egg cells. During meiosis, the number of chromosomes is halved to 23 to ensure that when fertilization occurs, the resulting zygote has 46 chromosomes, with half from the mother and half from the father.
If a cell of an organism has 46 chromosomes before meiosis how many chromosomes will exist in each nucleus after meiosis?
After meiosis in a cell that originally has 46 chromosomes, each resulting nucleus will have 23 chromosomes. This is due to the process of meiosis, which involves two rounds of cell division that result in the formation of four daughter cells, each with half the number of chromosomes as the original cell.
Why are chromosomes replicated before Mitosis but not prior to Meiosis II?
Chromosomes are replicated before Mitosis to ensure each daughter cell receives a complete set of genetic material. In Meiosis II, chromosomes are already duplicated from Meiosis I, so replication is not needed to maintain the proper chromosome number.
How many chromosomes are there in cells of humans after meiosis?
There are 23 chromosomes in a human cell following meiosis. Meiosis is sometimes called "reduction division". The first division of meiosis (meiosis I) halves the chromosome number. In humans, there are 46 chromosomes in the mother cell when it begins meiosis I. More precisely, there are 23 pairs, one of each pair having been inherited from each parent. This number (46 in humans) is the diploid number for the species. After meiosis, each cell has the haploid number (23 in humans), i.e. one of each chromosome in the set.
