Yes - the daughter cells produced in meiosis (gametes) have half the number of chromosomes as those in the original cell. This is why meiosis is referred to as 'reduction division'.
However, as meiosis produces cells which are involved in sexual reproduction - the chromosome number in the species remains constant. This is because when the two gametes combine, the resulting organism has the correct number of chromosomes (half from each gamete).
What else can I help you with?
In which stage of meiosis is the chromosome number halved?
The chromosome number is halved during the first stage of meiosis, known as meiosis I.
What happens to the chromosome numbers during meiois?
During meiosis, the chromosome number doubles because the cells replicate their DNA and split into two cells in meiosis I and in meiosis II, they replicate DNA and split once again, to form four cells.
How does the alternation of meiosis and fertilization in the life cycles of sexually reproducing organisms maintain the normal chromosome count for each species?
Simple, Meiosis reduce the chromosome number in half while fertilization doubles the chromosome number. n=chromosome number Meiosis = 2n (primordial germ cells) ----> n (sperm cell/egg cell/polar bodies) Fertilization = sperm (n) + egg (n) ----> 2n (zygote)
Why does meiosis go through its phases twice?
Meiosis involves two rounds of cell division (meiosis I and meiosis II) to reduce the chromosome number and ensure genetic diversity. The first division separates homologous chromosomes to produce haploid cells, and the second division separates sister chromatids to produce gametes with unique genetic combinations.
How is the chromosome number halved during cell division: mitosis or meiosis?
The chromosome number is halved during cell division in meiosis, not mitosis.
In which stage of meiosis is the chromosome number halved?
The chromosome number is halved during the first stage of meiosis, known as meiosis I.

How does the significance of meiosis maintained the chromosome number?
No. Meiosis results in halving of chromosome number. Chromosome number after one round of meiosis is half that of original chromosome number. Generally, meiosis takes place during gamete formation. So when two gametes fuse, they lead to restoration of the chromosome number. Hence chromosome number can be maintained in sexually reproducing organisms.
Are the chromosome copied before meiosis or during meiosis?
before
In what type of cell division does the chromosome number reduce by one half and gametes form?
Meiosis produces gametes which have half the number of chromosomes that other cells of the body have.
How does the alternation of meiosis and fertilization in the life cycles of sexually reproducing organisms maintain the normal chromosome count for each species?
Simple, Meiosis reduce the chromosome number in half while fertilization doubles the chromosome number. n=chromosome number Meiosis = 2n (primordial germ cells) ----> n (sperm cell/egg cell/polar bodies) Fertilization = sperm (n) + egg (n) ----> 2n (zygote)
Why does meiosis go through its phases twice?
Meiosis involves two rounds of cell division (meiosis I and meiosis II) to reduce the chromosome number and ensure genetic diversity. The first division separates homologous chromosomes to produce haploid cells, and the second division separates sister chromatids to produce gametes with unique genetic combinations.
What is the major focus of meiosis 1?
The major focus of meiosis 1 is to reduce the chromosome number by half. This is achieved through the processes of homologous chromosome pairing, crossing over, and separation of homologous chromosomes. Meiosis 1 results in two haploid cells with unique combinations of genetic information.
How is the chromosome number halved during cell division: mitosis or meiosis?
The chromosome number is halved during cell division in meiosis, not mitosis.
How is the chromosome number halved in mitosis or meiosis?
During meiosis, the chromosome number is halved through two rounds of cell division. In the first round, called meiosis I, homologous chromosomes separate, reducing the chromosome number by half. In the second round, called meiosis II, sister chromatids separate, resulting in the final halved chromosome number.
What process separates chromosome?
Mitosis and Meiosis
