In animals, the cells of the multicellular adult body are usually diploid (or sometimes polyploid), and the sex gametes (sperm and eggs) are haploid. Animals spend most of their life in the diploid genetic state, and only undergo meiosis at the time of gamete production.
What does meiosis in animals produce?
The name for the process by which an animal produces gametes. It is basically meiosis in animals.
Do animals use mitosis or meiosis?
somatic cells in animals can only undergo mitosis . Meiosis takes place in reproduction cells where the cells divide following procedural sequence.In a nutshell ,meiosis is for reproduction purposes while mitosis is for growth of new cells of other body parts ,somatic cells.
Why are animals gametes haploid?
Animals are diploid organisms (2n) and undergo sexual reproduction. This sexual reproduction causes them to produce gametes via a process called MEIOSIS. … This means that meiotic division produces haploid gametes (n) from a diploid animal.
Can gametes be produced by mitosis?
When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. … When a cell divides by way of meiosis, it produces four cells, called gametes. Gametes are more commonly called sperm in males and eggs in females.
Where does meiosis cell division occur in animals?
Gametogenesis | Back to Top
Oogenesis is the process of forming an ovum (egg) by meiosis (in animals, by mitosis in the gametophyte in plants) in specialized gonads known as ovaries. Whereas in spermatogenesis all 4 meiotic products develop into gametes, oogenesis places most of the cytoplasm into the large egg.
Where does meiosis take place in animals?
Meiosis takes place in the reproductive organs of the organism. For females, meiosis takes place in the ovaries, where the eggs are produced and…
