Implication

Comparative genomic analysis reveals high concordance between microsatellites and SNPs in cattle and sheep, highlighting microsatellites as cost-effective tools for livestock conservation.

Key Points

To compare the performance and consistency of microsatellites versus whole-genome single nucleotide polymorphism (SNP) chips for inferring population genetic structure in livestock breeds.
Evaluated three paired datasets of sheep and cattle breeds using both microsatellite markers and whole-genome SNP chips.
Assessed population genetic differentiation by calculating pairwise fixation index (FST) values and conducting STRUCTURE clustering analyses.
Fixation index (FST) and STRUCTURE analyses showed strong qualitative consistency between microsatellites and SNPs, although microsatellites provided less resolution.
Pairwise FST comparisons exhibited the highest concordance in a dataset of 17 French sheep breeds, yielding a Pearson correlation coefficient of r = 0.95 across 136 pairwise values.
