Modeling variance structure of body shape traits of Lipizzan horses.
Heterogeneity of variance of growth traits over age is a common issue in estimating genetic parameters and is addressed in this study by selecting appropriate variance structure models for additive genetic and environmental variances. Modeling and partitioning those variances connected with analyzing small data sets were demonstrated on Lipizzan horses. The following traits were analyzed: withe...
متن کاملEffects of inbreeding and heterozygosity on preweaning traits in a closed population of Herefords under selection.
Records of five inbred lines at the Livestock and Range Research Laboratory were used to evaluate effects of inbreeding and heterozygosity on preweaning traits. Members of each line were descendants of a single founder Hereford bull. A total of 8,065 records of birth weight and 7,380 records of preweaning daily gain and weaning weight were analyzed by derivative-free REML using a model that inc...

متن کاملEstimation of Inbreeding Coefficients Using Pedigree and Microsatellite Markers and Its Effects on Economic Traits of Shirvan Kordi Sheep
In this study, pedigree data of 7170 lambs produced from 177 rams and 2182 ewes collected during 1989 to 2009 in the Shirvan Kordi sheep breeding station, were used for calculating inbreeding coefficients. The impact of inbreeding on the studied traits was investigated by including inbreeding coefficients for each animal as a covariate in the animal model. Average inbreeding coefficient of the ...
متن کاملAssessment of the Genetic Diversity of Almond (Prunus dulcis) Using Microsatellite Markers and Morphological Traits
The genetic diversity among 56 almond (Prunus dulcis) genotypes was analysed using 35 microsatellite markers and 14 morphological traits. Analysis of morphological traits revealed a wide range of variation among the studied genotypes. Out of 35 simple sequence repeats (SSRs) markers, 25 were polymorphic, producing 215 alleles that varied from 2 to 16 with an average of 8.76 alleles per locus. R...
