DNA Replication. Before meiosis actually begins, the DNA that is packaged into chromosomes must be fully copied. Previous to replication, a germ cell contains two copies of each chromosome, a maternal copy, and a paternal copy
The pairing of homologous chromosomes before nuclear division occurs in meiosis. Meiosis is a type of cell division that results in the formation of sex cells (sperm and egg cells) with half the number of chromosomes as the parent cell.
Yes, interphase occurs before meiosis.
there is no difference between the meosis in males and females.
Before mitosis and meiosis, DNA is loose in the form of chromatin, then it coils into chromosomes right before the mitosis and meiosis.
Crossing over of genetic material occurs just before prophase 1 of meiosis, where homologous chromosomes exchange segments. This event does not occur before prophase 2 because homologous chromosomes have already separated during meiosis I.
It happens during interphase of the cell cycle.
If my memory does server me correctly, I am pretty sure it's Meiosis. Then again i think that happens after Mitosis. >.<
DNA is copied in meiosis 1.
One thing that happens in meiosis that does not occur in meiosis is that produces 2 cellular divisions. This occurs as a direct result of sexual reproduction.

Chromosomes make copies of themselves once during meiosis. This occurs during the S phase of interphase, which happens before meiosis I.
DNA is copied in meiosis 1.
Interphase. The process of meiosis has many similarities to the process of mitosis: chromosomes replicate before the process begins, and shorten and thicken to look like the chromosomes at the beginning of mitosis (condensation).
DNA is copied.
