How do meiosis and fertilization keep a species' chromosome number the same?

Meiosis is results in gametes (or sex cells) that have half the number of choromosomes as non-sex cells.
This means that when fertilization occurs, each gamete is carrying half the number of chromosomes - so when they combine, you end up with the number of chormosomes found in somatic (non-sex) cells.

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.....
Constancy of a chromosome number from one cell generation to the next is maintained through?
No of chromosomes is maintained by meiosis and fertilization .
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.
The process of meiosis and fertilization help ensure the survival of the species by providing each generation with the same number of?
chromosomes
What is the chromosome number during fertilization?
The zygote's number of chromosomes is double that of the two sex 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 is meiosis essential for sexual reproduction?
it is a reductional division so that at time of fertilization baby get half number of chromosome from the parents.

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).
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.
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.
