Discussion

Analysis demonstrates strong genetic diversity and potential heterosis in sheep breeds, highlighting crossing strategies for breed optimization.

High levels of genetic diversity were observed using microsatellite markers in five sheep breeds.
The genetic variation index (Fst) indicated moderate differentiation between populations in Shanxi Province.
Population genetic structure was illustrated through UPGMA clustering, revealing distinct relationships among breeds.
Crossing Guangling Large-Tail Sheep with other breeds may enhance heterosis, supporting hybrid breeding efforts.

Xue et al. (2025) studied this question.
