Heritability (h2:
It expresses the genetic variation of genotypic variation to the total phenotypic variation of the characteristic and ranges from zero to the correct one.
It can be calculated from the previous equation as follows:
σ2A / σ2P = h2
The genetic equivalence in the broad sense is sometimes calculated by calculating the total genetic variation (the cumulative, sovereign and exogenous effect of the genes) to the total phenotypic variance, which is limited in use:
σ2G / σ2P = h2
For example, the genetic equivalent of milk production in milk cows is 25-35%, milk fat 50%, fertility rate 5% and maturity size 40%. Therefore, the improvement of the milk production status, which has a genetic equivalent of the average value, Fertility traits with low genetic equivalence (0.05 to 0.1) are limited and slow, while attention to care and improved environmental conditions are better and more useful in such traits.
