gametogenesis

During the summer, they are in the sexual rest stage, and gametogenesis begins at the start of autumn.

Gametogonia are usually seen as the initial stage of gametogenesis.

The embryonic development doesn't differ from the male one, but follows the common path before gametogenesis.

An oocyte is produced in the ovary during female gametogenesis.

Populations have been found to synchronize their gametogenesis and spawning activities.

The production of gametes takes place within the gonads through a process known as gametogenesis.

If the adult mussels are stressed during the beginning of gametogenesis, the process is terminated.

It is the female form of gametogenesis; the male equivalent is spermatogenesis.

However, little is known about the underlying genetic mechanisms, which play a role in male sporo- and gametogenesis.

Halving of the chromosome number occurs at gametogenesis by meiosis.

This is due to a mis-segregation (nondisjunction) during gametogenesis.

Gametogenesis takes place for 5 months of the year, and most of these chitons will live through the reproduction cycle about 3 times.

This glycogen is then used to support gametogenesis during the next winter and early spring when food intake is at a minimum.

Centrosome reduction during gametogenesis and its significance.

This may occur under conditions of stress with the entire cytoplasm undergoing gametogenesis and the original organism being left as a husk.

DNMT3L is expressed during gametogenesis when genomic imprinting takes place.

Fertilization of the female gamete by the male gamete occurs rapidly after gametogenesis.

Because of this timing, an equal number of male and female clams are collected starting in the early fall when gametogenesis commences.

The gametogenesis was confirmed by the appearance of Pfg27, an early gamete-specific protein [ 30 ] .

The extra X chromosome is retained because of a nondisjunction event during meiosis I (gametogenesis).

The production of gameotypes is termed 'gametogenesis', during which phase gametocytes divide by meiosis into gametes.
