The genetic parameters usually studied refer to genetic variances in its addictive and non-addictive components, to heritability coefficient (lato and stricto sensu), and tothe interactions between genetic and environmental effects and genetic correlations among these characters (Silveira, 2007).
If bioassays are performed from only 1 or 2 egg dates, there is a great potential for the total genetic variance of the field-collected population to be under-represented.
The estimates of additive genetic variance and heritability from this study are not precise because of the small numbers of families and parents in this trial.
Aimed at students and experienced scientists studying DNA sequence alterations, this reference compares and evaluates the technical choices available in detecting genetic variances in the context of pharmacogenomics.
Af] is our symbol for the genetic variance among families.
Through a simple mathematical derivation, the genetic variance of z can be expressed by:
Non-iterative least square weighted analysis was applied for goodness of fit for genetic (additive genetic variance DR and dominance HR) and two environmental (within family environment E1 and between family environment E2) components.
As such, it is the most comprehensive evaluation of genetic variance in human metabolism to date, combining genetics and metabolomics for hypothesis generation in a GWAS.
The additive genetic variance across age at calving increased steadily till around 80 months and then drops till 130 months of calving and then tends to show a plateau till the end of age at calving.
Degree of dominance >one and ratio of GCA over SCA variance <unity showed that dominant genetic variance was larger than additive genetic variance for studied characters (Fellahi et al.
