  2. Gametogenesis - Wikipedia

    en.wikipedia.org/wiki/Gametogenesis

    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.

  3. Imprinting (psychology) - Wikipedia

    en.wikipedia.org/wiki/Imprinting_(psychology)

    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 ...

  4. G2 phase - Wikipedia

    en.wikipedia.org/wiki/G2_phase

    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 ]

  5. G1 phase - Wikipedia

    en.wikipedia.org/wiki/G1_phase

    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 ...

  7. Unconscious mind - Wikipedia

    en.wikipedia.org/wiki/Unconscious_mind

    In psychoanalysis and other psychological theories, the unconscious mind (or the unconscious) is the part of the psyche that is not available to introspection. [1] Although these processes exist beneath the surface of conscious awareness, they are thought to exert an effect on conscious thought processes and behavior. [2]

  8. Piaget's theory of cognitive development - Wikipedia

    This is important because the answers they give can help the experimenter to assess the child's developmental age. [53] Number of times asking: Some argue that a child's answers can be influenced by the number of times an experimenter asks them about the amount of water in the glasses. For example, a child is asked about the amount of liquid in ...

  9. Blastomere - Wikipedia

    en.wikipedia.org/wiki/Blastomere

    The division of blastomeres from the zygote allows a single fertile cell to continue to cleave and differentiate until a blastocyst forms. The differentiation of the blastomere allows for the development of two distinct cell populations: the inner cell mass, which becomes the precursor to the embryo, and the trophectoderm, which becomes the precursor to the placenta.
