Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes. During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote.
What happens to the 4 gametes?
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
What happens to the 4 daughter cells after meiosis?
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. … The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
Where will the male and female gametes be just before fertilization?
Male gametes are found inside tiny pollen grains on the anthers of flowers. Female gametes are found in the ovules of a flower.
Are the daughter cells identical in meiosis?
Like mitosis, meiosis is a form of eukaryotic cell division. … Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
Where does mitosis occur in the body?
Cell division by mitosis occurs in all human body cells except the gonads (sex cells). During mitosis, the DNA is exactly copied and a new daughter cell created with the same number of chromosomes as the parent cell, ie 46.
What does N mean in mitosis?
If a haploid cell has n chromosomes, a diploid cell has 2n (n represents a number, which is different for every species – in humans, for example, n = 23 and 2n = 46). … Therefore, if a diploid cell undergoes mitosis, the result is two identical diploid cells (2n →2n).
