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]
At the same time, the more extreme the expression of the trait in the parents, the more likely the child is to express the trait at all. For example, the child of two extremely tall parents is likely to be taller than the average person (displaying the trait), but unlikely to be taller than the two parents (displaying the trait at the same ...
However, many traits defy this simple categorization and the phenotypes are modelled by co-dominance and polygenic inheritance. [ 11 ] The term " wild type " allele is sometimes used to describe an allele that is thought to contribute to the typical phenotypic character as seen in "wild" populations of organisms, such as fruit flies ...
Eye color is an example of a (physical) phenotypic trait. A phenotypic trait, [1] [2] simply trait, or character state [3] [4] is a distinct variant of a phenotypic characteristic of an organism; it may be either inherited or determined environmentally, but typically occurs as a combination of the two. [5]
In 1060, the couple inherited the title via cognatic kinship from an Angevin family that was descended from a noble named Ingelger, whose recorded history dates from 870. [ 8 ] During the 10th and 11th centuries, power struggles occurred between rulers in northern and western France, including those of Anjou, Normandy , Brittany , Poitou ...
Epigenetic mechanisms. In biology, epigenetics is the study of heritable traits, or a stable change of cell function, that happen without changes to the DNA sequence. [1] The Greek prefix epi-(ἐπι-"over, outside of, around") in epigenetics implies features that are "on top of" or "in addition to" the traditional (DNA sequence based) genetic mechanism of inheritance. [2]
An acquired characteristic is a non-heritable change in a function or structure of a living organism caused after birth by disease, injury, accident, deliberate modification, variation, repeated use, disuse, misuse, or other environmental influence.
Meritocracy (merit, from Latin mereō, and -cracy, from Ancient Greek κράτος kratos 'strength, power') is the notion of a political system in which economic goods or political power are vested in individual people based on ability and talent, rather than wealth, social class, [1] or race.
