Meiosis typically occurs during the formation of reproductive cells (eggs and sperm) in organisms for sexual reproduction. In humans, meiosis happens during the formation of eggs (in females) and sperm (in males) during gametogenesis.

Which does not occur during meiosis?
DNA replication does not occur during meiosis. Meiosis is a specialized cell division process that involves two rounds of division to produce gametes with half the number of chromosomes as the parent cell. DNA replication happens during the interphase preceding meiosis.
Is meiosis necessary before fertilization Can occur?
Yes, meiosis is necessary before fertilization can occur because meiosis is the process by which gametes (eggs and sperm) are formed. During meiosis, the cell's chromosome number is halved, so that when the egg and sperm fuse during fertilization, the resulting zygote will have the correct number of chromosomes.
When does the first cell division in meiosis occur?
The first cell division in meiosis, known as meiosis I, occurs after the DNA in the cell has been replicated during the S phase of the cell cycle. Meiosis I involves the separation of homologous chromosomes.
In which structure or organs does meiosis formation of male gametes and or female gametes occur in animals?
Meiosis formation of male gametes (sperm) occurs in the testes of animals, while meiosis formation of female gametes (eggs) occurs in the ovaries. These structures are specialized for the production and maturation of sex cells through the process of meiosis.
In what structure does meiosis occur in bryophytes?
Meiosis in bryophytes occurs in specialized structures called sporangia. These sporangia house the cells that undergo meiosis to produce spores, which are later dispersed and germinate into the gametophyte stage of the bryophyte life cycle.
When does duplication of chromosomes occur?
when does the duplication of chromosomes occur?
What happens in meiosis that does not occur in meiosis?
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.
What happens in meiosis you that does not occur in meiosis?
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.
What occurs in meiosis i that does not occur in meiosis ii?
DNA is copied.
What structure does meiosis occur in bryophyte?
Meiosis occurs in the sporophyte.
What happens in meiosis I that does that occur in meiosis Ii?
DNA is copied.
What does meiosis occur in?
gonads
What type of cells does meiosis occur in?
Meiosis occurs in gametes or reproductive cells.
What happens in meiosis that does not occur in meiosis 2?
DNA is copied (for novanet cheaters)
What happens in meiosis 1 that doesnt occur in meiosis 2?
dna is copied
Does cell replacement occur in mitosis or meiosis?
Its meiosis. Mitosis is cell division.
In what stage of meiosis does this occur?
synapis
