HERITABILITY Meaning and
Definition
-
Heritability is a term used in genetics and evolutionary biology to measure the extent to which genetic differences contribute to phenotypic or observable differences in a population. It refers to the proportion of phenotypic variation in a particular trait that can be attributed to genetic variation among individuals within a population. In simpler terms, heritability quantifies the degree to which genes influence the variation of a particular trait within a population.
Heritability is often expressed as a value between 0 and 1, where 0 represents complete reliance on environmental factors, and 1 indicates that all the variation in a trait is due to genetic differences. However, it is important to note that heritability measures the relative contribution of genetic and environmental factors in a particular population at a specific time and place, and does not provide a precise estimate of the actual genetic component.
This concept is particularly useful in understanding the inheritance and evolution of traits. High heritability for a trait indicates that genetic factors play a significant role in its variation, while low heritability suggests that the trait is primarily influenced by environmental factors. Studying heritability can help researchers understand whether genetic or environmental interventions would be more effective in modifying a particular trait within a population.

Etymology of HERITABILITY
The word "heritability" is derived from the noun "heritable", which originated from the Old French word "heritable" in the 14th century. The Old French term was derived from the Latin word "hereditabilis", which means "able to be inherited". The Latin term itself was derived from the word "hereditas", meaning "inheritance" or "heritage". The word "heritability" emerged in the early 20th century to describe the degree to which variations in traits within a population can be attributed to genetic factors and passed down through generations.
