Estimation of heterogeneous genetic (co)variances in closed herds under selection



Estimation of heterogeneous genetic (co)variances in closed herds under selection



Proceedings of the 8th World Congress on Genetics Applied to Livestock Production, Belo Horizonte, Minas Gerais, Brazil, 13-18 August, 2006: 03-55



The objective of this trial was to study the possibility of using a multiple regression model to estimate components of additive genetic (co)variance along cycles of selection in a closed herd with generation overlapping. Programs in fortran language were developed to fit in the regression. The determination coefficients (R2) were high and did not vary much, with a mean of 0.90272 and a standard deviation of 0.03936.
