crossing over of chromosomes, indepependent segregation of chromosomes and mutations
The purpose of synapsis is to increase genetic variability
Meiosis
No.
If you mean meiosis I and meiosis II, then no they are not identical, but meiosis II does follow meiosis I.
The steps in the diploid life cycle are meiosis, to gametes, to fertilization, to diploid, to reproductive cell. The main steps are Meiosis and Fertilization.
The purpose of synapsis in meiosis is to increase genetic variability. It does this as the homolog pairs match up, which means there are 4 chromosomes of like, but possibly unique, DNA data in the grouping. This allows the cell. as it proceeds through Anaphase 1 and Anaphase 2 to separate the individual chromosomes first into 2 pairs then as individuals, which inturn adds to the variability as 1 chromosome goes to each daughter cell. .

The crossing over of genetic material during meiosis is directly correlated with the production of genetic variability in daughter cells. Crossing over occurs during prophase I of meiosis when homologous chromosomes exchange genetic material, leading to new combinations of genes in the daughter cells.
Synapsis creates genetic variability. So the haploid cells produced during meiosis will be different. If this didn't happen, one successful virus is all it would take to eradicate the human race.
All steps of meiosis II are similar to the steps of Mitosis
