Abstract:
Heritability is one of the most important genetic
parameters found in connection with the decisions that must be taken in the
breeding processes. The component of the total variation genetically
determined depended on the frequency of the gene and on the development
of the substitution effect of the gene. The variation of the gene frequency
from one population to another and the changes produced by the action of
some factors in the same population affected the component of the genetic
variance and the ratio of the variance within the population and, finally, the
increase of the heritability coefficient. The determination of heritability was
necessary especially if populations are found in the middle of the breeding
process having the objective of modifying the genetic structure.
