Premeiotic, post meiotic, pre mitotic, or postmitotic events are all possibilities if imprints are created during male and female gametogenesis. However, if only one of the daughter cells receives parental imprints following mitosis, this would result in two functionally different female gametes or two functionally different sperm cells.
In psychology and ethology, imprinting is any kind of phase-sensitive learning (learning occurring at a particular age or a particular life stage) that is rapid and apparently independent of the consequences of behaviour. It was first used to describe situations in which an animal or person learns the characteristics of some stimulus, which is ...
Though Wee1 is a fairly conserved negative regulator of mitotic entry, no general mechanism of cell size control in G2 has yet been elucidated. Biochemically, the end of G 2 phase occurs when a threshold level of active cyclin B1 / CDK1 complex, also known as Maturation promoting factor (MPF) has been reached. [ 4 ]
Between the beginning of the G 1 phase (which is also after mitosis has occurred) and R, the cell is known as being in the G 1-pm subphase, or the post-mitotic phase. After R and before S, the cell is known as being in G 1-ps, or the pre S phase interval of the G 1 phase. [4]

The result however has been challenged by others who claimed that this is an overestimation by an order of magnitude due to flawed statistical analysis. [ 33 ] [ 34 ] In domesticated livestock, single-nucleotide polymorphisms in imprinted genes influencing foetal growth and development have been shown to be associated with economically ...
