Heritability can also change as a result of changes in the environment, migration, inbreeding , or the way in which heritability itself is measured in the population under study. [9] See more Heritability is a statistic used in the fields of breeding and genetics that estimates the degree of variation in a phenotypic trait in a population that is due to genetic variation between individuals in that population. The concept of … See more Since only P can be observed or measured directly, heritability must be estimated from the similarities observed in subjects varying in their level of genetic or environmental similarity.
