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. Through heredity, variations between individuals can accumulate and cause species ...
A hereditary monarchy is a form of government and succession of power in which the throne passes from one member of a ruling family to another member of the same family. A series of rulers from the same family would constitute a dynasty. It is historically the most common type of monarchy and remains the dominant form in extant monarchies.
A study of 39 non-Western societies found many customs that distinguished between children according to their sex and birth order. First sons, in comparison to other sons, "are likely to inherit or otherwise gain control of more family land, livestock, or other wealth." First sons inherited more than the other sons among 11 societies studied.

Hereditary titles, in a general sense, are nobility titles, positions or styles that are hereditary and thus tend or are bound to remain in particular families. Though both monarchs and nobles usually inherit their titles, the mechanisms often differ, even in the same country.
Genetics is, generally, the study of genes, genetic variation, and heredity. The process by which characteristics are passed down from parents to their offspring is called heredity. In the sense of classical genetics, variation is known as the lack of resemblance in related individuals and can be categorized as discontinuous or continuous.
The Arakkal kingdom followed a similar matrilineal system of descent: the eldest member of the family, whether male or female, became its head and ruler; the male rulers were called Ali Rajah and the female rulers were called as Arakkal Beevis. Usually after one king, his nephew through his sister succeeded to the throne, and his own son ...
Heritability may be estimated by comparing parent and offspring traits (as in Fig. 2). The slope of the line (0.57) approximates the heritability of the trait when offspring values are regressed against the average trait in the parents. If only one parent's value is used then heritability is twice the slope.
