I understand that gametes are produced through the process of meiosis. I'm just wondering, do gametes ever undergo a form of mitosis where it is replicated to produce more gametes after the initial meiosis stage is over?
MathewsMD said:The "best answer" in the following link says: "these cells continue dividing, producing billions of sperm cells per day." Is this correct? Do sperm undergo countless divisions (mitosis) once they are formed in the haploid phase?

Off the top of my head, a close phenomenon might be the mitosis of haploid yeast cells.
MathewsMD said:Another question closely related: in females, is there a general range of maximum potential ova? How many gametes do females develop by the end of gestation?
Gametes are specialized cells involved in sexual reproduction. They are haploid cells, meaning they contain half the number of chromosomes compared to other cells in the body.
Yes, gametes undergo a process called meiosis where they replicate their DNA and divide into four haploid cells. This is necessary for the formation of genetically diverse offspring.
The purpose of gamete replication is to produce genetically diverse offspring by combining genetic material from two parent cells. This increases genetic variation in a population, which is important for the survival of a species.
No, mitosis does not occur in gametes. Mitosis is a type of cell division that results in two identical daughter cells. Gametes, on the other hand, undergo meiosis, which results in four genetically diverse daughter cells.
No, gametes are not produced continuously. They are only produced during specific stages of an organism's life cycle, such as during sexual maturity. In humans, gametes are produced through meiosis in the ovaries and testes.
