Retinoschisis is an eye disease characterized by the abnormal splitting of the retina's neurosensory layers, usually in the outer plexiform layer.Retinoschisis can be divided into degenerative forms which are very common and almost exclusively involve the peripheral retina and hereditary forms which are rare and involve the central retina and sometimes the peripheral retina.
Retinoschisin also known as X-linked juvenile retinoschisis protein is a lectin [5] [6] that in humans is encoded by the RS1 gene. [7]It is a soluble, cell-surface protein that plays an important role in the maintenance of the retina where it is expressed and secreted by retinal bipolar cells and photoreceptors, [8] [9] as well as in the pineal gland.

However, there is more genetic diversity in Africa than the rest of the world combined, [82] so speaking of a "Black" race is without a precise genetic meaning. [81] Qualitative research has fostered arguments that behavioural genetics is an ungovernable field without scientific norms or consensus, which fosters controversy.
Retinitis pigmentosa (RP) is a member of a group of genetic disorders called inherited retinal dystrophy (IRD) that cause loss of vision. [1] Symptoms include trouble seeing at night and decreasing peripheral vision (side and upper or lower visual field). [1]
In psychology, genetic memory is a theorized phenomenon in which certain kinds of memories could be inherited, being present at birth in the absence of any associated sensory experience, and that such memories could be incorporated into the genome over long spans of time.
The most popular theory behind this association is a separation of the layers of the retina, known as retinoschisis, due to fluid (the vitreous humour) entering the optic pit and traveling between the inner and outer layers of the retina. The outer layer may then subsequently detach. Evidence of retinoschisis has been demonstrated using OCT.
The basic principle behind psychiatric genetics is that genetic polymorphisms (as indicated by linkage to e.g. a single nucleotide polymorphism) are part of the causation of psychiatric disorders. [1] Psychiatric genetics is a somewhat new name for the old question, "Are behavioral and psychological conditions and deviations inherited?".
The missing heritability problem was named as such in 2008 (after the "missing baryon problem" in physics).The Human Genome Project led to optimistic forecasts that the large genetic contributions to many traits and diseases (which were identified by quantitative genetics and behavioral genetics in particular) would soon be mapped and pinned down to specific genes and their genetic variants by ...
