additive genetic effects

Genetic effects which occur when the combined effects of alleles at different loci are equal to the sum of their individual effects.

Models ranged in the orders of the Legendre's polynomial used to adjust the additive genetic effects and permanent environmental effects.
Shared (familial) environmental effects are negligible, and additive genetic effects are partly shared between As and Hg.
In general, additive genetic effects explained greater percentages of family variation than dominance genetic effects.
The results of testing of models of sources of variation, including additive genetic effects (A), dominance genetic effects (D), common environmental effects shared by members of a twin pair regardless of zygosity (C), and nonshared environmental effects (E), are shown in Data Supplement Table DS3.
If the MZ correlation coefficient is twice the DZ correlation coefficient, then additive genetic effects likely influence self-reported health.
The main reason for this was that preliminary comparative analysis involving several different TD models have shown that for the data and population in question a RRMs with second order Legendre polynomial for permanent environmental and additive genetic effects were found to be the best by most model selection criteria.
a is a random vector of direct additive genetic effects of animal for the trait,
Thus, the mixed animal model contained contemporary group, calving age, and additive genetic group as fixed effects, and animal additive genetic effects and residual as random effects.
3] are corresponding design matrices related to the fixed effects, direct additive genetic effects, maternal additive genetic effects and maternal permanent environmental effects to vector y.
Animal additive genetic effects considering pedigree relationship and residual errors were assumed with random effects.
Heredity of economic and reproductive traits in living organisms results from genetic and environmental factors, with maternal and direct additive genetic effects being of great importance among the genetic factors.
