For both CRP and SAA, the pattern of variances and covariance in the twins was best explained by a model that contained only additive genetic and unique environmental variance components (AE model).
Nevertheless, it is notable that the increase in variation for BPb is entirely attributable to an increase in environmental variance, regardless of whether this is a cohort or an aging effect.
Additive genetic and permanent environmental variance components for test day milk traits in Black-White cattle.
A mixed model was employed to estimate genetic and environmental variance components as following:
2]]e are direct additive genetic variance, maternal additive genetic variance, maternal permanent environmental variance and residual variance, respectively.
e] are direct additive genetic variance, maternal additive genetic variance, maternal permanent environmental variance and residual variance, respectively; A is the additive numerator relationship matrix; Id and In are identity matrices that have order equal to the number of dams and number of records, respectively.
The heritability estimates decreased with the order of lactation mainly as a result of increased environmental variance, and estimates from repeated records model are generally lower than those estimated with first lactation (Visscher and Thompson, 1992).
For maternally influenced traits, maternal permanent environmental variance as a proportion of phenotypic variance was higher than estimates of maternal heritabilities.
Genetic variance from model 2 or that from model 4 was less than those from models 1 or 3 while environmental variance and phenotypic variance from model 3 was less than those from the other three models.
Estimates of permanent environmental variance (Table 3) for total sperm cells were close to zero and did not differ across age classifications.
