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.
What is meiosisI?
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.
The normal species chromosome number is called the what number?
During cell division the parent cell splits to form what 2 cells
Change in chromosome number in mitosis and meiosis?
Meiosis results in a change in chromosome number indicated by division of cells into two identical cells. This is a process that is used for purposes of reproduction.
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.
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.
What division is sexual?
It is a division that reduces the number of chromosomes to half of their number before the division.
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.
What best describes the function of meiosis?
reduces chromosome number by half, produces gametes
Mitosis is cell division in which the chromosome number is what?
Mitosis is cell division in which the chromosome number stays the same. Although at some points throughout the cell cycle, chromosomes may consist of two sister chromatids
If the chromosome number of a typical onion root tip cell is sixteen before mitosis what is the chromosome number of the each newly formed nucleus after nuclear division has taken place?
the same as before, each will have sixteen. If it was meyoses it would be 1/2 that (8) Mitotic division creates exact replicates of the original, so the answer is 16. Meosis occurs in the flower of the onion, it's sex cells ovules and pollen will have only 8 chromosomes
Explain the importance of crossing-over during the first division of meiosis?
The first division reduces the number of Chromosomes by half.
what process reduces the chromosome number of a cell by half?
Well, meiosis splits a cell into two daughter half-cells.
What are the definition and stages of meiosis?
There are 12 stages of meiosis. Meiosis is a type of cell that is dived, which reduces the chromosome number by half.
What is meiosisI?
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.
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.
How does the number of chromosome in the two new cells compare with the number in the original cell at the end of cell division?
with the identical sisters chromatid
