What is the process that serves to decrease cellular chromosome number by half?

During meiosis the number of chromosomes per cells is cut in half through the separation of homologous chromosome in a diploid cell. Meiosis is the process of cell division that reduces the number of chromosomes.

Meiosis consists of two successive nuclear divisions. During the first division, meiosis I, each homologous pair of chromosomes is split, one chromosome to each daughter-cell. This halves the number of chromosomes.

Pairing between homologous chromosomes during prophase of meiosis I and separation of these chromosomes during anaphase I result in halving the number of chromosomes in a cell.
Mitosis, on the other hand, is when you double the number of cells with the full DNA. A way to remember that one apart from meiosis is to think of a "toe." To regenerate the cells in your toe, you would use mitosis.
Also, do not confuse this with miosis. That is the narrowing of the pupils in the eye. Mydriasis (dilation) is its opposite.

What decrease cellular chromosome number by half is?
Meiosis.
What process changes the order but not the number of genes on a chromosome?
Inversion
What process union of egg and sperm restores chromosome number?
Fertilization.
How does DNA or chromosomes cause hemophilia?
The "X" chromosome . . . I believe it is number 23 . . .
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.....

Meiosis.
One gamete is formed during what process?
The cellular chromosome number is reduced from 2N to 1N.
How does mitosis conserve chromosome number while meiosis reduces the number from diploid to haploid?
Short Answer: the [it appears] one, extra, cellular process that only Meiotic Cells possess is termed "Chromosome Reduction"; we have seen (elsewhere) that this process results in the reduction of Chromosome Number from the mitotic {somatic} 2N to the Meiotic {gametic} 1N.
What happen to the chromosome number in each process?
they duplicate
What is the process that results in changing of chromosome number?
Non-disjunction
What process changes the order but not the number of genes on a chromosome?
Inversion
What process union of egg and sperm restores chromosome number?
Fertilization.
Which sequence of terms represents a decrease from the greatest number of structures to the least number present in a cell?
gene,chromosome THEN nucleus :) HOPE YOU DO WELL !!
