What else can I help you with?
Does DNA replication happen before or during Meiosis?
It happens during interphase of the cell cycle.
What happens during the first division of meiosis that does not happen in meiosis?
In Meiosis I: Separates homologous chromosomes In Meiosis II: Separates sister chromatids
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 happens in meiosis that does not happen in meiosis 2?
DNA is copied in meiosis 1.
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 1 that does not happen in meiosis 2?
DNA is copied in meiosis 1.
What would happen during a plants life cycle if meiosis did not occur?
We'd die from lack of reproduction.
Do crossovers usually occur during mitosis?
No, crossovers do not occur during mitosis. Crossovers, also known as genetic recombination, happen during meiosis, specifically during prophase I. Mitosis is the cell division process that results in two identical daughter cells, while meiosis is the cell division process that results in four genetically unique daughter cells.
If a child is born with down syndrome when did the mutation occur?
During meiosis
When does replication happen during mitosis or meiosis?
Replication occurs during the S phase of the cell cycle before both mitosis and meiosis. In mitosis, the replicated DNA is separated into two identical daughter cells. In meiosis, the replicated DNA is separated into four haploid daughter cells with genetic variation.
What happens in meiosis 1 that doesn't happen in meiosis 2?
DNA is copied
