In the second meiotic division, the chromosomes in each cell align independently and randomly at the equator of the cell. It is important because without this division, chromosome copies would double at each fertilization.

During first meiotic division the number of chromosomes is just reduced to half by pairing of homologous chromosomes in prophase I to interchange the chromatic material for new genetic combinations in the adjoining chromatids. The separation of chromosomes from the bi-valents without the division of centromere of individual chromosome brings about reduction in their number to just half. Thus 50 percent of gamete cells are provided with new genetic combinations.

Explain the importance of crossing-over during the first division of meiosis?
The first division reduces the number of Chromosomes by half.
When does the first cell division in meiosis occur?
When the chromosome is :
What will separate in the first division in meiosis one?
chromosomes
What stage of meiosis is the chromosome number reduced?
In Anaphase I
What type of cell division produce the sperm and egg cell?
it is formed by meiosis. At first the spermatazoa go through mitosis making two spermatocytes. which then goes through meiosis producing 4 spermatids which then go through spermogenisi n make 4 sperm cells
Explain the importance of crossing-over during the first division of meiosis?
The first division reduces the number of Chromosomes by half.
What stage of of meiosis do homologous pairs separate?
Reduction Division
What is the separation of homologous pairs of double chromosomes during meiosis?
the stage is called the "first division"
What happens during the first division of meiosis that does not happen in meiosis?
In Meiosis I: Separates homologous chromosomes In Meiosis II: Separates sister chromatids
When does the first cell division in meiosis occur?
When the chromosome is :
What will separate in the first division in meiosis one?
chromosomes
What does the term reduction division mean?
Cell division in which the volume of the two daughter cells does not increase. The result is a progressive increase in cell number, without a corresponding increase in the size of the tissue. Reductive divisions are characteristic of cleavage in early embryos.
Is duplication of paired chromosomes in the first stage of meiosis?
Yes duplication of chromosomes occurs during the first stage of meiosis or during prophase.
If a cell that undergoes meiosis later is four cells with chromosome numbers 17 17 18 and 16 what happened?
one of the sister chromatids in one of the two cells that was produced during the first division of meiosis did not separate during the second division resulting in one cell with an extra chromosome and one with a missing chromosome. This process is known as nondisjunction
What is produced from diploid germ cells by meiosis?
4 Haploid gametes. In Meiosis, germ cells first undergo a mitosis like division which produces 2 diploid germ cells. After that division, they undergo a second division in Meiosis 2, without first replicating their chromosomes. The end result is 4 haploid gametes.
What is interkinsis?
Interkinesis is the period between the first and second divisions in meiosis. Meiosis is a special type of cell division of genetic material (DNA). Meiosis produces genetic diversity.
What stage of meiosis is the chromosome number reduced?
In Anaphase I
