When eggs and sperm are made, the DNA splits off in halves. Then when a sperm joins an egg, they recombine to form a new piece of DNA which is two perfect halves. Sometimes there is more or less info, this leads to defects which will prevent breeding, since people with the defect don't breed, the defect doesn't spread rapidly.

How the chromosomal number of the cell is kept constant through mitosis?
By uniform replication of DNA and division of centomeres, the daughter nuclei receive the same number of chromosomes.
How is the chromosomal number of a cell kept constant throughout mitosis?
yes it is, in mitosis, a cell with a diploid number (2n) of chromosomes eg 46, will produce daughter cell of equal nd diploid number of chromosomes(46)
Mitosis is the division of?
nuclearIt is the division of the nucleus. Here the chromosomal number is not changed.
Will chromosomal complement of daughter cells?
The chromosomal complement of daughter cells depends on the type of cell division occurring. In mitosis, daughter cells receive an identical set of chromosomes as the parent cell, maintaining the same chromosomal complement. In meiosis, the daughter cells have half the number of chromosomes, resulting in a haploid complement, which is essential for sexual reproduction.
How is the chromosome number affected by cell division?
During cell division, the chromosome number remains constant. In mitosis, each daughter cell receives an identical set of chromosomes to the parent cell. In meiosis, the chromosome number is halved to produce gametes with half the number of chromosomes as the parent cell.

Why do cells need mitosis?
So they can surviveThey are important in increasing number of cells. It maintains chromosomal number
Does the chromosomal number change at all during mitosis?
No. Mitosis produces identical daughter cells - same DNA and same amount. Only in meiosis does the chromosome number halve.
How is the chromosomes number halved during cell division: through mitosis or meiosis?
The chromosomes number is halved during cell division through meiosis, not mitosis.
Why must gametes undergo meiosis instead of mitosis?
Gametes don't undergo Meiosis, but are CREATED in Meiosis.Gametes should be haploid. Otherwise chromosomal number will be doubled in offspring
How many cells does mitosis create?
2They are identical cells. They have same chromosomal number
Why are root tip and embryo cells good for studying mitosis?
Root tip and embryo cells are good for studying mitosis because they are actively dividing cells, providing a large number of cells in various stages of mitosis for observation. This allows researchers to capture different phases of the cell cycle. Additionally, these cells have less cytoplasm and a simpler structure, making it easier to visualize the chromosomal movements during mitosis.
What is the product of mitosis in the cell cycle?
The product of mitosis in the cell cycle is two daughter cells that are genetically identical to the original parent cell. Mitosis is responsible for cell replication and growth, ensuring that each daughter cell receives a complete set of chromosomes.
Why cant mitosis provide for the sexual reproduction of offspring that contain the same number of chromosomes as the parents?
Mitosis produces two identical daughter cells with the same number of chromosomes as the parent cell. However, sexual reproduction requires the combination of genetic material from two parents to create offspring with genetic variation. This variation is achieved through meiosis, where the chromosome number is halved and genetic recombination occurs.
Why do cells go through division on mitosis?
To increase the number of somatic cells.
