of meiosis involves duplication and then separation of the chromosomes, followed by division into two daughter cells that each contain half the number of chromosomes as the original cell. In the second phase, each daughter cell divides to form an additional reproductive cell. See Note atmitosis. ...
Gametes (sex cells) are haploid cells. When gametes are joined, the resulting cell has two sets of chromosomes.

Mitosis Mitosis occurs when a cell makes an exact copy of itself then splits, producing two diploid daughter cells with identical sets of chromosomes. Mitosis is a form of asexual reproduction, growth, or tissue repair. Haploid Number The haploid number is the number of chromosomes within thenuc...
Mitosis after meiosis leads to the formation of female gametophytes and male gametophytes (pollen). One haploid sperm cell (SC) fertilizes the haploid egg cell (EC). This develops into the diploid embryo. The other sperm fertilizes the diploid central cell (CC), generating the triploid ...
is divided by half generating cells with only one set of chromosomes. These cells are calledhaploidsand are represented by the symbol(n). Haploid cells are formed after a cell undergoes a type of cell division calledmeiosis. Diploid cells, on the other hand, are generated bymitosis. ...

A cell with three or more chromosome sets is called polyploid. A haploid cell can become diploid cell in a process called diploidization. A diploid cell can also become polyploid cell in a process called polyploidization. Di‐ and polyploidization result often from endomitosis, a process in ...
human somatic cell (which is 46). Atfertilization, the two cells unite forming a zygote with now two sets of chromosomes. The human zygote, then, grows by going through mitosis. As a result, the archetypal chromosomal number of 46 in humans per somatic cell in the human body is ...
Haploid (n) chromosome numbers were determined from cells in diakinesis, metaphase I, and metaphase II of meiosis. FromProject Gutenberg Technically the tissue-cells are said to contain the diploid number of chromosomes, the gametes the reduced or haploid number. ...
the process of meiosis. Diploid cells undergo mitosis. In the higher organism, such as humans, haploid cells are only used for sex cells. In the higher organism, such as humans, all other cells beside sex cells are diploid. Examples of haploid cells aregametes (male or female germ cells)...
