The objective of this project was to determine the genetic control of conception rate, or
pregnancy percentage in Angus beef heifers. Producers from 6 herds in 5 states provided 3,144 …

Historically, dwarfism was the major genetic defect in US beef cattle. Aggressive culling and
sire testing were used to minimize its prevalence; however, neither of these practices can …

Background Marginal posterior genotype probabilities need to be computed for genetic
analyses such as geneticcounseling in humans and selective breeding in animal and plant …

Abstract Information from cosegregation of marker and QTL alleles, in addition to linkage
disequilibrium (LD), can improve genomic selection. Variance components linear models have …

Under additive inheritance, the Henderson mixed model equations (HMME) provide an
efficient approach to obtaining genetic evaluations by marker assisted best linear unbiased …

QTL allele state and allele origin probabilities are used in linear model methods to map QTL.
When data are from complex pedigrees, MCMC methods are useful to compute these …

For a finite locus model, Markov chain Monte Carlo (MCMC) methods can be used to estimate
the conditional mean of genotypic values given phenotypes, which is also known as the …

means under finite locus models with BLUP evaluations indicate that a small number of loci …

Computer simulation was used to examine the relationship between the number of loci
included in the model and the accuracy of whole-genome methods for genetic evaluation. …
