Gametes in mitosis?

  1. Dec 14, 2013 #1
    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?

    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?

    http://www.ncbi.nlm.nih.gov/books/NBK10019/ - it looks like the primordial germ cells are diploid, so that doesn't seem to be what you are asking about.

    Off the top of my head, a close phenomenon might be the mitosis of haploid yeast cells.

    Thanks for the great link. Although it doesn't answer my question directly, it's helpful in understanding why this is more likely.

    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?

    They are primary oocytes and millions of eggs are in a fetus but it is only when you start ovulating that they are officially considered gametes.
