Genomic prediction in insects: a case study on wing morphology traits in the jewel wasp Nasonia vitripennis

This paper applies genomic prediction to wing morphology traits in Nasonia vitripennis using GBLUP and GBS data, finding higher accuracy in 5-fold cross-validation than across-generation validations.

How partial phenotyping to reduce generation intervals can help to increase annual genetic gain in selected honeybee populations

This study shows that reducing the generation interval in honeybee breeding by focusing on early traits can increase genetic gain, though it requires strategies to manage inbreeding.

Quantifying Key Parameters of Environmental Transmission and Age-Specific Susceptibility for Mycobacterium avium subspecies paratuberculosis (MAP)

The paper estimates key parameters for MAP transmission and age-specific susceptibility using dose-response and environmental transmission models based on published experiments.

Uncertainty in the mating strategy causes bias and inaccuracy in estimates of genetic parameters in honeybees

The paper investigates how uncertainty in honeybee mating strategies affects genetic parameter estimates and proposes methods to correct biases in genetic evaluations.

The long-term effects of genomic selection: 2. Changes in allele frequencies of causal loci and new mutations

This study examines how genomic selection affects allele frequencies and new mutations over fifty generations, finding that genomic selection leads to faster and larger changes in allele frequencies compared to pedigree selection.

The long-term effects of genomic selection: Response to selection, additive genetic variance and genetic architecture

This study simulates the long-term effects of genomic selection on genetic architecture, showing that non-additive effects significantly impact genetic variance and allele frequency changes over generations.

The quantitative genetics of the prevalence of infectious diseases: hidden genetic variation due to Indirect Genetic Effects dominates heritable variation and response to selection

This paper develops a quantitative genetic theory for infectious disease prevalence, showing indirect genetic effects dominate heritable variation and response to selection.

Required marker properties for unbiased estimates of the genetic correlation between populations

The paper investigates how marker allele frequencies and linkage disequilibrium affect estimates of genetic correlation between populations, finding that marker allele frequencies should reflect causal loci frequencies for unbiased estimates.

Properties Of Genomic Relationships For Estimating Current Genetic Variances Within And Genetic Correlations Between Populations

This paper defines a multi-population genomic relationship matrix to estimate current genetic variances within populations and genetic correlations between populations, and validates its properties through simulations.
