Does DNA replication happen before or during Meiosis?
It happens during interphase of the cell cycle.
When a child has Trisomy when does the mutation occur?

What happens during the first division of meiosis that does not happen in meiosis?

What happen to the organism when something goes wrong during meiosis?
it can go really weird
What happen to chromosomes during meiosis?
half of each parents' chromosomes go to the offspring
What would happen if crossing over during meiosis didn't happen in humans?
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.
What happens in meiosis that does not happen in meiosis 2?
DNA is copied in meiosis 1.
If a child is born with down syndrome when did the mutation occur?
During meiosis
What phase happens only once in meiosis?
Interphase only happens once during meiosis. Prophase, metaphase, anaphase, telophase and cytokinesis all happen twice.
What would happen during a plants life cycle if meiosis did not occur?
We'd die from lack of reproduction.
What event occurs in an organism when a chromosome is not copied correctly during meiosis?
