The pairing of homologous chromosomes before nuclear division happens in what type of cell division?
The pairing of homologous chromosomes before nuclear division occurs in meiosis. Meiosis is a type of cell division that results in the formation of sex cells (sperm and egg cells) with half the number of chromosomes as the parent cell.
What is the process called that guarantees that the number of chromosomes in gametes is half the number of chromosomes in body cells is?
Since gametes divide by a special process, meiosis, they will always have half the number of chromosomes as regular body cells. This is because the chromosomes only copy themselves once, however they are split apart twice. Think of it as a math problem. If the original cell count is, for example, 2 chromosomes, and each chromosome makes a copy of itself, the cell will have 4 chromosomes. During meiosis 1, the cell divides, and the chromosomes split, resulting in each daughter cell having 2 chromosomes, the same as the original. However, in meiosis 2, they divide again without making another copy of themselves, so that by the time meiosis is done, each one of the 4 cells that results have 1 chromosome, half the number of the original cell. 2x2=4 4/2=2 2/2=1
Gametes are produced by meiosis rather than mitosis because?
Gametes are produced by meiosis rather than mitosis because meiosis generates haploid cells with half the number of chromosomes, which is necessary for sexual reproduction to maintain the correct chromosome number in the offspring. Mitosis produces diploid cells with the same number of chromosomes as the parent cell.
What is the ploidy of animal cells that are capable of meiosis?
Animal cells that are capable of meiosis are typically diploid, meaning they have two sets of chromosomes. During meiosis, these diploid cells undergo two rounds of cell division to produce haploid gametes with only one set of chromosomes.
Do homologous chromosomes separate only in meiosis?
Yes, homologous chromosomes separate only during the first division of meiosis, known as meiosis I. This separation ensures that each daughter cell receives one complete set of chromosomes.
Does meiosis increaase the number of chromosomes in a cell?
No, it halves it. This is because Meiosis is only used in the production of sex cells (gametes), and two gametes are needed for a zygote to be created, and each carries half the normal number of chromosomes. When they join together during fertilization their offspring will carry the normal number of chromosomes.
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.....
What is the number of chromosomes in daughter cells in humans during meiosis?
Meiosis produces daughter cells with half as many chromosomes as the parent cell. This means that because a normal human cell has 46 chromosomes, a gamete (produced through meiosis) will only contain 23 chromosomes.
Why is meiosis only for sex cells?
Only diploid cells can undergo meiosis because haploid cells have a single set of chromosomes that can't be furthered reduced. Gametes form through meiosis.
The net result of meiosis is to reduce the number of chromosomes in gametes to only one from each?
homologous

What do chromosomes and meiosis have to do with each other?
Chromosomes carry genetic information, which is passed on during the cell division process of meiosis. Meiosis involves two rounds of cell division that result in the formation of gametes (sperm and egg cells) with half the number of chromosomes as the parent cell, allowing for genetic diversity through the random assortment of chromosomes.

How do the product's of meiosis compare to the original cell?
Meiosis results in 4 haploid daughter cells with only half the number of chromosomes of the original cell.
What does meiosis produce in gamete?
Meiosis produces gametes which have only one set of chromosomes for that species.
What does gametic meiosis produce?
Meiosis produces gametes which have only one set of chromosomes for that species.
