The acoelomate theory, which states that coelom evolved from an acoelomate ancestor. The enterocoel theory, which states that coelom evolved from gastric pouches of cnidarian ancestors. This is supported by research on flatworms [ citation needed ] and small worms recently discovered [ clarification needed ] in marine fauna [ citation needed ...
Mendelian inheritance (also known as Mendelism) is a type of biological inheritance following the principles originally proposed by Gregor Mendel in 1865 and 1866, re-discovered in 1900 by Hugo de Vries and Carl Correns, and later popularized by William Bateson. [1] These principles were initially controversial.
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.
Enterocoelom (adjective forms: enterocoelic and enterocoelous) describes both the process by which some animal embryos develop and the origin of the cells involved. In enterocoely, a mesoderm (middle layer) is formed in a developing embryo, in which the coelom appears from pouches growing and separating from the digestive tract (also known as the embryonic gut, or archenteron).

An example of the codominant inheritance of some of the four blood groups. Mendelian traits in humans are human traits that are substantially influenced by Mendelian inheritance. Most – if not all – Mendelian traits are also influenced by other genes, the environment, immune responses, and chance.
In the development of the human embryo, the intraembryonic coelom (or somatic coelom) is a portion of the conceptus forming in the mesoderm during the third week of development. [1]
Classical genetics is often referred to as the oldest form of genetics, and began with Gregor Mendel's experiments that formulated and defined a fundamental biological concept known as Mendelian inheritance. Mendelian inheritance is the process in which genes and traits are passed from a set of parents to their offspring.
With de novo mutations and division errors, the relationship between the offspring's altered genes and gene inheritance from the parents is technically spurious. [13] These genetic errors can affect the mind as well as the body and can result in schizophrenia , [ 14 ] [ 15 ] autism , [ 11 ] bi-polar disorder , [ 16 ] and cognitive [ 17 ...
