meiosis occour only in sexual cells and its reduce the number of chromosomes so when the sperm cell fuse with ovum cell the number of chromosomes it will be the same as in parents cell.
Humans cells have 46 chromosome
sperm cells have 23 chromosomes
ovoum cells 23 chromosomes
when sperm cell fertilize the ovun they fuse their genetic material and we have
23+23=46
every cell in our body it has 46 chromosome except sexual cells
What else can I help you with?
Both meiosis and fertilization are essential to maintain chromosome number constant .why?
Total number of chromosomes remain same in same species of organism through meiosis process. In meiosis process the number of chromosomes are reduced to half as a result in gametes only one set of chromosomes will be present. In this process chromosomes are same.....
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.
What is necessary for meiosis to produce cells with fewer chromosomes?
Meiosis requires two rounds of cell division, meiosis I and meiosis II, to reduce the chromosome number by half. During meiosis I, homologous chromosomes are separated, and in meiosis II, sister chromatids are separated. This process ensures that each resulting gamete contains a haploid set of chromosomes, which is essential for sexual reproduction, allowing for the restoration of the diploid number upon fertilization. Additionally, proper pairing and recombination of homologous chromosomes during prophase I are crucial for genetic diversity.
What is the order of fertilization sex cells meiosis zygote mitosis?
The order would be: Meiosis -> sex cells -> fertilization -> zygote -> mitosis Meiosis creates sex cells, called gametes, which combine during fertilization to create a zygote. The zygote then undergoes mitosis.
Why is it necessary for meiosis to produces cells with fewer chromosomes?
If it did not, the chromosome number would double in each generation.
Is meiosis necessary before fertilization Can occur?
Yes, meiosis is necessary before fertilization can occur because meiosis is the process by which gametes (eggs and sperm) are formed. During meiosis, the cell's chromosome number is halved, so that when the egg and sperm fuse during fertilization, the resulting zygote will have the correct number of chromosomes.
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 must meiosis occur before fertilization?
Meiosis is necessary before fertilization because it reduces the chromosome number by half in the gametes, ensuring that when the egg and sperm fuse during fertilization, the resulting zygote has the correct number of chromosomes. This process is essential for genetic diversity and the successful development of the offspring.
Why is it necessary to have two separate divisions in meiosis?
Having two separate divisions in meiosis is necessary to reduce the chromosome number by half, ensuring that the resulting gametes have the correct number of chromosomes. This reduction is essential for sexual reproduction, as the fusion of two gametes during fertilization will restore the full chromosome number in the offspring.

When and why does meiosis occur?
Meiosis occurs in sexually-reproducing organisms during the formation of gametes (sperm and egg cells). It is necessary to reduce the chromosome number by half, ensuring that when the gametes combine during fertilization, the resulting offspring will have the correct number of chromosomes.
Why does meiosis result 1N cells rather than 2N cells?
Meiosis is a two-step process that reduces the chromosome number by half, resulting in 1N cells. This reduction is necessary for sexual reproduction so that when the male and female gametes combine during fertilization, the resulting zygote has the correct 2N chromosome number.
Meiosis in a sentence?
Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the formation of haploid gametes necessary for sexual reproduction.
What k must happen before meiosis can begin?
A duplication of the chromosomes is what must happen before meiosis can begin.
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.
Meiosis is significant to most living organisms because it?
allows sexual reproduction to maintain the diploid chromosome number. (apex)
