half of each parents' chromosomes go to the offspring
Chromosomes separate during the anaphase stage of meiosis or mitosis. During this stage the chromosomes move to the opposite ends of the cell.
If crossing over didn't happen during meiosis in humans, the haploid daughter cells would all have the same genes. The crossing over creates variation and causes each daughter cell to have slightly different genes.
technically the chromosomes copy during interphase right before metaphase I of meiosis I so during Meiosis I the chromosomes are duplicated and not until metaphase II during meiosis II are the sister chromatids separated.
Before Meiosis 2, the cell must first go through Meiosis 1. This is when the cell splits into two cells, each with two chromosomes.
Interkinesis or interphase II is a period of rest that cells enter during meiosis. It is the abbreviated interphase that occurs between meiosis I and II. No DNA replication occurs during this stage of Meiosis. Many plants skip telophase I and interkinesis, going immediately into prophase II. Each chromosome is still composed of two chromatids.

Mitosis results in the formation of more somatic cells and meiosis creates haploid cells for gametophytic stage

The four stages of Mitosis is: Prophase: the first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes. Metaphase:the stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate of the spindle fibers Anaphase:The stage of mitosis and meiosis in which the chromosomes move to opposite ends of the nuclear spindle fiber. Telophase: The final stage of mitosis or meiosis during which the chromosomes of daughter cells are grouped in new nuclei.
