Meiosis I produces two cells, both of which are haploid. This means each cell has half the number of chromosomes as the parent cell. This is a crucial step in sexual reproduction, promoting genetic diversity.
Meiosis I produces two cells, each of which is haploid.
During the process of meiosis, a cell initially has two copies of each chromosome, one from the mother and one from the father (46 in humans). This is called a diploid state. However, after meiosis I, it splits into two cells each containing half the number of chromosomes (23 in humans). These cells are said to be haploid because they only possess one copy of each chromosome. The division which occurs during meiosis I is a fundamental part of the sexual reproduction process, as it leads to genetic diversity in offspring.
