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 the significant of meiosis sexual reproduction?
Meiosis forms sex cells (eggs and sperm). Meiosis randomly rearranges the genes on chromosomes through crossing-over of chromatids of homologous chromosomes. Meiosis reduces the chromosome number from two sets to one set maintaining a constant chromosome number in the offspring
What happens to the chromosomes number by the end of meiosis?
The chromosome number at the end of meiosis is half of the parent cell
What decrease cellular chromosome number by half is?
Meiosis.

Does meiosis reduce chromosome numbers?
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).

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)

How meiosis maintain a constant number of chromosome within a species?
Meiosis creates gametes (sperm and ova/eggs) which are involved in sexual reproduction. The result of meiosis is cells with half the number of chromosomes as a somatic (non-sex) cell. This ensures that when the gametes join during sexual reproduction, the resulting organism has the correct number of chromosomes (half from each gamete). Thus meiosis maintains the chromosome number.
What is Meiosis definition?
Meiosis is the type of cell division that results in gametes (sex cells) that possess half the chromosome number of the parent cell. In other words, meiosis reduces the chromosome number by one-half.
How is the chromosome number affected by cell division?
In Mitosis, the chromosome number remains the same. In meiosis, the number of chromosomes is halved.
During meiosis the chromosome number does what?
During meiosis, the chromosome number decreases by half. For example, if a human cell with 46 chromosomes were to undergo meiosis, the result would be four daughter cells with 23 chromosomes in each.
