Compare and contrast meiosis I and meiosis II.
Understand the Problem
The question is asking for a comparison and contrast between meiosis I and meiosis II, which are two stages of the meiosis process involved in sexual reproduction. It will focus on the key differences and similarities in terms of processes, outcomes, and stages between meiosis I, which reduces chromosome number and involves homologous chromosome pairing, and meiosis II, which resembles mitosis and separates sister chromatids.
Answer
Meiosis I reduces the chromosome number by separating homologous chromosomes into two haploid cells, while meiosis II separates sister chromatids into four haploid cells.
Meiosis I involves the separation of homologous chromosomes and reduces the chromosome number by half, producing two haploid cells. Meiosis II involves the separation of sister chromatids, resulting in four haploid daughter cells, without changing chromosome number.
Answer for screen readers
Meiosis I involves the separation of homologous chromosomes and reduces the chromosome number by half, producing two haploid cells. Meiosis II involves the separation of sister chromatids, resulting in four haploid daughter cells, without changing chromosome number.
More Information
Meiosis I is also known as reductive division because it reduces the number of chromosomes by half. Meiosis II is similar to mitosis and is called equational division.
Tips
Avoid confusing homologous chromosomes with sister chromatids. Remember that homologous chromosomes are similar but not identical and come from each parent; sister chromatids are identical copies formed during DNA replication.
