They replicate before meiosis begins, as it is the division phase. The chromosomes duplicate during interphase which is right before the beginning of meiosis. After going through meiosis I the chromosomes DO NOT duplicate nor do they cross over they simply continue on. Hope this helps. :)

What happens before meiosis begin?
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).
How many times do chromosomes make copies of themselves during meiosis?
2
How many chromosomes are present when meiosis is started?
In humans, 46 chromosomes are present when meiosis begins. The four daughter cells that result from meiosis have 23 chromosomes.
How many ways can cell replicate?
Two meiosis and mitosis
Why does meiosis result in half as many chromosomes as the original cell?
Because in meiosis the chromosomes don't line up

How do cells Replicate?
Cells replicate for many reasons, they replicate by a process of mitosis or meiosis. Mitosis producing two daughter cells and meiosis producing gamete cells (sperm or ovum(egg) )
