Animal model estimation of additive and dominance variances in egg production traits of poultry.
An animal model analysis was used to estimate simultaneously additive (sigma 2a) and dominance (sigma 2d) variances for egg production traits within three White Leghorn lines. The data consisted of information for three generations on egg number (EN) produced at 18 to 25 (EN1), 26 to 65 (EN2), and 18 to 65 wk of age (EN3); egg weight (EW) measured at 30 to 35 (EW1) and 40 to 45 wk (EW2); and eg...
متن کاملEstimates of Genetic Variances and Level of Dominance in Maize.
HE dominant favorable gene hypothesis, first proposed by BRUCE (1910), T attributes heterosis to accumulated effects of loci at which the more favorable allele contributed by one parent is manifest rather than the unfavorable allele contributed by the other parent. The concepts of linkage (JONES 191 7) and large number of loci (COLLINS 1921; SINGLETON 1941) make the hypothesis compatible with t...
متن کاملEstimation of genetic parameters for quantitative and qualitative traits in cotton cultivars (Gossypium hirsutum L. & Gossypium barbadense L.) and new scaling test of additive– dominance model
A complete diallel cross of nine cotton genotypes (Gossypium hirsutum L. & Gossypium barbadense L.) viz Delinter, Sindose-80, Omoumi, Bulgare-539, Termez-14, Red leaf (Native species), B-557, Brown fiber and Siokra-324 having diverse genetic origins was conducted over two years to determine the potential for the improvement of yield, its components, oil and fiber qual...
متن کاملVariances of additive and dominance genetic effects for ovulation and twinning rates in a population selected for twinning.
Estimates of variances due to additive and dominance genetic effects and permanent and temporary environmental effects were obtained for ovulation and twinning rates from a composite population selected for twinning rate. Measures of ovulation rate after 11 mo of age on 2,317 heifers with a total of 19,209 measures were used. Twinning measures were on 1,522 first-parity cows, 1,311 later-parity...
متن کاملEfficient Markov chain Monte Carlo implementation of Bayesian analysis of additive and dominance genetic variances in noninbred pedigrees.
Accurate and fast computation of quantitative genetic variance parameters is of great importance in both natural and breeding populations. For experimental designs with complex relationship structures it can be important to include both additive and dominance variance components in the statistical model. In this study, we introduce a Bayesian Gibbs sampling approach for estimation of additive a...
