Webcombined effect of the heritability, the amount of genetic variation present, the selection intensity and the cycle length (season per cycle). If heritability of a character is very high e.g., 0.8 or more, selection for the character should be fairly easy because there would be a close correspondence between genotype and phenotype. WebFinally, heritability within a population can change over time, and for that reason, should be estimated at regular intervals. Misconception 5. “A high heritability implies a major …
