At the end of meiosis, from the initial diploid cell, you end up with
(1, 2, 3, 4) (diploid, haploid) cells?
At the end of meiosis, from the initial diploid cell, you end up with four haploid cells.
Here's an explanation of how meiosis leads to the formation of haploid cells from a diploid cell:
1. Meiosis is a two-step cell division process that occurs in sexually reproducing organisms. It is responsible for the formation of gametes (sperm and eggs) which are haploid cells.
2. Meiosis starts with a diploid cell, which means it has two sets of chromosomes, one inherited from each parent. Each set of chromosomes consists of homologous pairs, meaning they have corresponding genes.
3. The first step of meiosis, called meiosis I, involves the separation of homologous pairs of chromosomes. This results in the formation of two daughter cells, each with one set of chromosomes, but still consisting of replicated sister chromatids.
4. The second step of meiosis, called meiosis II, is similar to a regular cell division (mitosis). In this step, the sister chromatids are separated, resulting in the formation of four haploid daughter cells.
So, at the end of meiosis, you have four haploid cells, each containing one set of chromosomes. These haploid cells are genetically unique and ready to combine with another haploid cell during fertilization to form a new diploid organism.
