Meiosis I:
* Homologous chromosomes pair up: During prophase I, homologous chromosomes (one from each parent) come together and pair up.
* Crossing over occurs: Genetic material is exchanged between the homologous chromosomes, creating new combinations of alleles.
* Homologous chromosomes separate: During anaphase I, the homologous chromosome pairs are pulled apart, with one chromosome from each pair going to each of the two daughter cells.
Meiosis II:
* Sister chromatids separate: The two daughter cells from Meiosis I enter Meiosis II, where the sister chromatids within each chromosome are separated.
* Four haploid cells result: The end result of Meiosis II is four haploid cells, each with half the number of chromosomes as the original parent cell.
In summary: Meiosis is designed to reduce the number of chromosomes by half, ensuring that offspring inherit one chromosome from each parent. This process of separating homologous chromosomes in Meiosis I and sister chromatids in Meiosis II results in four daughter cells with only one copy of each chromosome, thus not having paired chromosomes.
