:Both sexes have the potential to undergo spontanous mutation during gametogenesis, but as correctly pointed out by Sifaka, oogenesis is basically complete at the time of birth, and no new eggs are generated in adulthood.

Development before birth, including gametogenesis, embryogenesis, and fetal development, is the process of body development from the gametes are formed to eventually combine into a zygote to when the fully developed organism exits the uterus.

So that, rather than providing selective advantages through reproduction, sex could be thought of as a series of separate events which combines step-by-step some very weak benefits of recombination, meiosis, gametogenesis and syngamy.

The transgenic mice thus generated are viable, demonstrating that there are c-fos dependent and independent pathways of cell proliferation, but display a range of tissue-specific developmental defects, including osteoporosis, delayed gametogenesis, lymphopenia and behavioral abnormalities.

While this nuclear import process does make up the majority of the functional role of importin ? proteins, several other important functions have been shown to be mediated by importin ?s including gametogenesis, development, heat shock response, protein degradation, and viral pathogen infection.

The X-linked reproductive homeobox, known as RHOX, is the only set of homeobox genes that have been shown to have roles in gametogenesis . [ 9 ] The RHOX homeobox is a cluster of genes that are selectively expressed in both the male and female reproductive tract in mice and humans.

According to this hypothesis, disturbances to organelles, including autophagy ( normal cell destruction ), gametogenesis ( the formation of gametes ), and cell stress, release DNA which is imported into the nucleus and incorporated into the nuclear DNA using non-homologous end joining ( repair of double stranded breaks ).
