Meiosis: Each daughter cell's chromosome number gets halved.---Haploid cells(n)
Mitosis: Each chromosome number stays the same.------------------Diploid cells(2n)

∙ 13y agoMeiosis is the way sex cells are produced. Each sex cell (in a human) has 23 chromosomes, so if you like, meiosis reduces the number of chromosomes in the cell by a half. A better way of putting this is when the producing cell divides, it splits its chromosomes into two, passing one half onto each new cell, rather than replicating itself.

Meiosis reduce the number of chromosomes by?
by half.
Why is meiosis necessary after fertilization to maintain chromosome number?
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
How was it possible to predict that meiosis occurred before there was direct visual evidence for it?
It was possible to predict meiosis before direct visual evidence because the behavior of chromosomes during cell division was observed, and scientists noticed that the number of chromosomes in the daughter cells was half that of the parent cell. This observation led to the hypothesis that a special division process, later called meiosis, must be occurring to reduce the chromosome number.
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.
During what phase is the chromosome number reduced from 2n to n?
Homologous chromosomes travel to opposite sides of the cell
Meiosis reduce the number of chromosomes by?
by half.
The net result of meiosis is to reduce the number of chromosomes in gametes to only one from each?
homologous
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).
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.
State the purpose of meiosis?
the purpose of meiosis is to reduce the number of chromosomes in new cells to half the number of the original cell which is known as reduction division. The process also creates gamete cells which are also haploid cells because they contain half the DNA of the original cell.In simple terms the purpose of meiosis is to create genetically unique sex cells ( sperm and egg ) with half the normal number of chromosomes

When and why does meiosis occur?
It occurs to reduce the number of gametes.

Why must sperm and egg cells reduce their number of chromosomes before they fuse?
They must reduce their number of chromosomes by half so that way when they do fuse, the two halves of genetic material equal a full cell.

Homologous chromosomes travel to opposite sides of the cell
