The polymorphism at the Pvu II recognition site in the ESR gene showed no statistically significant association with sow productivity traits in a Meishan × Large White F 2 population. Estimates of the effect on litter size were, however, in the opposite direction and statistically different from previously published estimates. Taken together with results from other publications, results here indicate that this Pvu II polymorphism displays different degrees of linkage disequilibrium with a gene or genes controlling litter size in different populations.
