[ 12 ] [ 13 ] In Oomycota and some other organisms, the female oogonia, and the male equivalent antheridia , are a result of sexual sporulation, i.e. the development of ...
Oogonium: diploid/46: 2C: Oocytogenesis : third trimester primary Oocyte: diploid/46: 4C: Ootidogenesis (meiosis 1) (Folliculogenesis) -- polar body separated: Dictyate in prophase I until ovulation secondary Oocyte: haploid/23: 2C: Ootidogenesis (meiosis 2) -- polar body separated: Halted in metaphase II until fertilization Ootid: haploid/23 ...
The development of the gonads is part of the prenatal development of the reproductive system and ultimately forms the testicles in males and the ovaries in females. The immature ova originate from cells from the dorsal endoderm of the yolk sac. Once they have reached the gonadal ridge they are called oogonia.

Germ cells are specified early in development [4] and can only differentiate into gametes. [5] The segregation of germ cells is often determined by the species, with some undergoing preformation, where the germ cells are determined by maternally inherited factors before or immediately after fertilisation, and others undergoing epigenesis, where the germ cell lineage is determined from ...
