Explain how the number of chromosomes per cell is cut in half during meiosis in which the diploid parent cell produces haploid d
2 answers:
It happens through 3 stages
- Interphase
- Meiosis 1
- Meiosis 2
In Meiosis one the cell produces diploid daughter cells by combining homogeneous and heterogeneous chromosomes.
In Meiosis two these diploids again tear apart to produce haploid daughter cells
Meiosis in Humans
In humans, meiosis is the process by which sperm cells and egg cells are produced. In the male, meiosis takes place after puberty. Diploid cells within the testes undergo meiosis to produce haploid sperm cells with 23 chromosomes. A single diploid cell yields four haploid sperm cells through meiosis.
Stages of meiosis
Meiosis contains two separate cell divisions, meaning that one parent cell can produce four gametes (eggs in females, sperm in males). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.
Before entering meiosis I, a cell must first go through interphase. This is the same interphase that occurs before mitosis. The cell grows, copies its chromosomes and prepares for division during the G_1 start subscript, 1, end subscript phase, S phase, and G_2 start subscript, 2, end subscript phase of interphase.
Meiosis I
Meiosis I is the first round of cell division, in which the goal is to separate homologous pairs.
Meiosis II
The second round of cell division is meiosis II, in which the goal is to separate sister chromatids.
