Heritability is specific to a particular population in a particular environment. Ver mais 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 … Ver mais Any particular phenotype can be modeled as the sum of genetic and environmental effects: Phenotype (P) = Genotype (G) + Environment (E).
