Mating is initiated by gametogenesis that produces small, motile gametes that fuse to form a small binucleate cell.
12.
The deletion event occurs randomly during gametogenesis ( formation of eggs or sperm ) or in early foetal development.
13.
The extra chromosome is retained because of a nondisjunction event during paternal or maternal meiosis I ( gametogenesis ).
14.
However, little is known about the underlying genetic mechanisms, which play a role in male sporo-and gametogenesis.
15.
Other studies suggest that eventual seminal regulator targets may be identified allowing with alterations to the massive epigenetic reprogramming during gametogenesis.
16.
This glycogen is then used to support gametogenesis during the next winter and early spring when food intake is at a minimum.
17.
Male and female FANCG mutant mice have defective gametogenesis, hypogonadism and impaired fertility, consistent with the phenotype of FA patients.
18.
Though this is not always the case, genetic mutations can occur spontaneously in one sex cell of a parent during gametogenesis.
19.
This may occur under conditions of stress with the entire cytoplasm undergoing gametogenesis and the original organism being left as a husk.
20.
As the oocyte is a product of female gametogenesis, the maternal contribution to the oocyte and consequently the newly fertilized egg is enormous.
