Mitosis
the process of mitosis, where a cell divides to produce two daughter cells with the same number of chromosomes as the original cell. Mitosis ensures that each daughter cell receives an identical set of chromosomes, maintaining the constancy of the chromosome number.
Genes are the heritable factors that retain their identity generation after generation. Genes are passed down from parents to offspring through the transmission of DNA, which contains the instructions for building and maintaining an organism's traits. This continuity of genes ensures that certain characteristics and traits are consistently inherited across different generations.
Sex cells must have half the chromosome number of normal body cells because during fertilization, when sperm and egg cells join, the resulting zygote will have the correct chromosome number. This ensures genetic diversity in offspring and helps maintain the stability of the species' chromosome number.
During sexual reproduction, the correct number of chromosomes is maintained through a process called meiosis, which reduces the chromosome number in half. This ensures that when two gametes (sperm and egg) combine during fertilization, the resulting zygote has the correct number of chromosomes for that species.
Meiosis is a specialized form of cell division that reduces the chromosome number by half, producing gametes (sperm and eggs) with a haploid set of chromosomes. When fertilization occurs, these gametes combine to restore the diploid chromosome number in the resulting zygote. This process ensures that each generation maintains the species' characteristic chromosome number, preventing any increase or decrease in genetic material over successive generations. Thus, meiosis plays a crucial role in preserving genetic stability within a species.

During cell division, the chromosome number is maintained through the processes of mitosis and meiosis by ensuring that each daughter cell receives the correct number of chromosomes. In mitosis, the replicated chromosomes are separated equally into two daughter cells, while in meiosis, the chromosomes are divided twice to produce four daughter cells with half the original number of chromosomes. This ensures that the chromosome number is maintained in the offspring cells.

mytosis creates sex cells - either eggs (in girls) or sperm (in boys). They have 1/2 the number of chromosomes. When an egg and sperm combine, they create one full cell - one half plus one half = one whole. The fetus is created from that one full cell.

Mitosis results in two identical cells being produced from the original cell. A copy of each chromosome is made before the cell divides and one of each chromosome goes to each new cell.
