Impact of population structure in the estimation of recent historical effective population size by the software GONE
CONCLUSIONS: Different kinds of deviations from isolation and panmixia of the populations can generate biases in the recent historical estimates of Ne. Therefore, estimation of past demography could benefit from performing population structure analyses beforehand, by mitigating the impact of these biases on historical Ne estimates.PMID:38049712 | PMC:PMC10694967 | DOI:10.1186/s12711-023-00859-2 (Source: Genet Sel Evol)

Genetic correlations of direct and indirect genetic components of social dominance with fitness and morphology traits in cattle
CONCLUSIONS: We present evidence that social dominance is genetically correlated with fitness traits, as well as empirical evidence of the possible evolutionary trade-offs between these traits. We show that it is feasible to estimate genetic correlations involving dyadic social traits.PMID:38037008 | PMC:PMC10687847 | DOI:10.1186/s12711-023-00845-8 (Source: Genet Sel Evol)

Micro-genetic environmental sensitivity across macro-environments of chickens reared in Burkina Faso and France
CONCLUSIONS: The results show that the heritability of the micro-GES of BW varies with macro-environment, which indicates that responses to selection are expected to differ between macro-environments. The weak to moderate positive genetic correlations between subpopulations indicate that both macro-environmental differences and purebred-crossbred differences can cause re-ranking of sires based on their estimated breeding values for micro-GES of BW. Thus, the sire that produces the most variable progeny in one macro-environment may not be the one that produces the most variable offspring in another. Similarly, the sire that...

Sequenced-based GWAS for linear classification traits in Belgian Blue beef cattle reveals new coding variants in genes regulating body size in mammals
CONCLUSIONS: Our study further supports that a set of common genes controls body size across mammalian species. In particular, we added new genes to the list of those associated with height in both humans and cattle. We also identified new strong candidate causal variants in some of these genes, strengthening the evidence of their causality. Several breed-specific recessive deleterious variants were identified in our QTL regions, probably as a result of the extreme selection for muscular development in BBB cattle.PMID:38017417 | PMC:PMC10683324 | DOI:10.1186/s12711-023-00857-4 (Source: Genet Sel Evol)

Heterogeneity in convergence behaviour of the single-step SNP-BLUP model across different effects and animal groups

Defining valid breeding goals for animal breeds
CONCLUSIONS: The proposed approach coincides with the traditional approach if the producers have the sole desire to maximize their income, and if consumer preferences are well reflected by the product prices. If these assumptions are not met, then the traditional approach to breeding goal optimization is unlikely to result in a valid breeding goal. Using the example of companion breeds, this paper shows that the proposed approach has the potential to fill the gap.PMID:37990149 | PMC:PMC10664641 | DOI:10.1186/s12711-023-00855-6 (Source: Genet Sel Evol)

Unravelling the genetic variability of host resilience to endo- and ectoparasites in Nellore commercial herds
CONCLUSIONS: Selection for BW under natural infestation and controlled parasite burden, via prophylactic parasite control, contributes to the identification of animals that are resilient to nematodes and Eimeria ssp. Although we verified that sufficient genetic variation existed for HR, we did not find any genes associated with mechanisms that could justify the expression of HR to TICK and GIN.PMID:37990289 | PMC:PMC10664541 | DOI:10.1186/s12711-023-00844-9 (Source: Genet Sel Evol)
