Where does the reduction of chromosomes occur in meiosis?
Cells undergoing meiosis are diploid. Reduction of chromosomes occurs in meiosis-1 to form 2 cells which undergo meiosis-2 to form four haploid cells (having half the number of chromosomes of the cell that undergoes meiosis). Meiosis 2 is just like mitosis.
In what stage of meiosis does the actual reduction of chromosome number occurs?
The actual reduction in chromosomes occurs in Anaphase 1 of Meiosis 1 as the bivalents split in this phase as the bivalents are separated and each cell receives half the no. of chromosomes.
How is chromosome number reduced in meiosis?
During meiosis, cell division makes the number of chromosomes get reduced to only a half of the original. Four new daughter haploid cells are produced from the original cell, and each have distinct genes from the parent cell.
In what part of meiosis does the reduction in chromosomes from diploid to haploid occur?
In anaphase I, centromeres break down and homologous chromosomes separate. In telophase I, chromosomes move to opposite poles; during cytokinesis the cell separates into two haploid cells.
Where does mitosis occur in the body?
Mitosis is an active process that occurs in the bone marrow and skin cells to replace cells that have reached the end of their lives. Mitosis occurs in eukaryotic cells. Although the term mitosis is frequently used to describe the entire process, cell division is not mitosis.
