On the origin and diversification of Podolian cattle breeds: testing scenarios of European colonization using genome-wide SNP data
During the Neolithic expansion, cattle accompanied humans and spread from their domestication centres to colonize the ancient world. In addition, European cattle occasionally intermingled with both indicine ca... (Source: Genetics Selection Evolution)

Genetic diversity and effective population sizes of thirteen Indian cattle breeds
The genetic structure of a diverse set of 15 Indian indigenous breeds and non-descript indigenous cattle sampled from eight states was examined, based on 777 k single nucleotide polymorphism (SNP) genotypes ob... (Source: Genetics Selection Evolution)

Genomic prediction using a reference population of multiple pure breeds and admixed individuals
In dairy cattle populations in which crossbreeding has been used, animals show some level of diversity in their origins. In rotational crossbreeding, for instance, crossbred dams are mated with purebred sires ... (Source: Genetics Selection Evolution)

Tests of association based on genomic windows can lead to spurious associations when using genotype panels with heterogeneous SNP densities
Dense single nucleotide polymorphism (SNP) panels are widely used for genome-wide association studies (GWAS). In these panels, SNPs within a genomic segment tend to be highly correlated. Thus, association stud... (Source: Genetics Selection Evolution)

Assessment of trade-offs between feed efficiency, growth-related traits, and immune activity in experimental lines of layer chickens
In all organisms, life-history traits are constrained by trade-offs, which may represent physiological limitations or be related to energy resource management. To detect trade-offs within a population, one pro... (Source: Genetics Selection Evolution)
