What is the main difference between meiosis II and mitosis in terms of chromosome behavior?

In meiosis II, homologous chromosomes are separated, while in mitosis, sister chromatids are separated.
In meiosis II, there is no genetic material replication, while in mitosis, the DNA does not replicate.
In meiosis II, sister chromatids are separated, while in mitosis, homologous chromosomes are separated. (correct)
In meiosis II, no separation of chromosomes occurs, while in mitosis, sister chromatids are separated.

Why are you not an exact replica of your siblings even though you have the same parents?

As a result of identical segregation of sister chromatids in meiosis II.
Because the crossing over of genetic material occurs during meiosis II.
Due to the random assortment of homologous chromosomes during meiosis I. (correct)
Due to the absence of genetic recombination in mitosis.

What event in meiosis is responsible for creating new combinations of genetic material in each resulting daughter cell?

Separation of homologous chromosomes in anaphase II
Meeting in the metaphase plate during metaphase II
Crossing over during prophase I (correct)
Separation of sister chromatids in anaphase I

Meiosis II vs. Mitosis: Chromosome Separation

In meiosis II, sister chromatids separate. In mitosis, homologous chromosomes separate.

Why siblings aren't identical

The random assortment of chromosomes during meiosis I ensures that each sperm or egg cell receives a unique combination of maternal and paternal chromosomes.

Creating new gene combinations in meiosis

Crossing over during prophase I allows exchange of genetic material between homologous chromosomes, creating new combinations of genes.

Meiosis II and Mitosis similarities

Meiosis II and mitosis both aim to produce new cells by replicating genetic material, leading to similar chromosome behavior during their respective anaphases.
