what is the biggest difference between the separation of chromosomes in meiosis and meiosis 2

easy and make simple

1 answer

The biggest difference between the separation of chromosomes in meiosis and meiosis II is:

  • Meiosis (specifically Meiosis I): Homologous chromosomes (pairs of similar chromosomes, one from each parent) are separated. This reduces the chromosome number by half, so each new cell gets one chromosome from each pair.

  • Meiosis II: The sister chromatids (identical copies of a chromosome) are separated. This is similar to what happens in mitosis, and the chromosome number stays the same in each cell produced.

In summary, Meiosis I separates pairs of chromosomes, while Meiosis II separates sister chromatids.
