Thus ... 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 heritability can be expressed in the form of the following question: "What is the … Zobacz więcej Heritability measures the fraction of phenotype variability that can be attributed to genetic variation.
