- Mussels > 20 mm are typically reproductive, however it is not uncommon for mussels up to 35 mm to have no signs of gametogenesis.
- His research has shown a lot of promise and progress in the areas of meiosis, gametogenesis and apomixis ( asexual reproduction ) in plants.
- A "'gametocyte "'is a eukaryotic germ cell that divides by mitosis into other gametocytes or by meiosis into gametids during gametogenesis.
- FANCC (-/-) mutant male and female mice have compromised gametogenesis, leading to markedly impaired fertility, a characteristic of Fanconi anemia patients.
- To explain the adaptive function of meiosis ( as well as of gametogenesis and the sexual cycle ), some authors emphasize diversity, and others emphasize DNA repair
- Hybridogenesis implies that during gametogenesis hybrids ( of RL genotype ) exclude one parental genome ( L or R ) and produce gametes with an sexually, recombined.
- The study suggested that snakes living under stressful conditions such as high population densities or low prey resources had suppressed reproduction at multiple stages including steroidogenesis and gametogenesis.
- Almost all of the methylations from the parents are erased, first during gametogenesis, and again in early embryogenesis, with demethylation and remethylation occurring each time.
- Therefore, during gametogenesis, primordial germ cells must have their original biparental DNA methylation patterns erased and re-established based on the sex of the transmitting parent.
