Divergent Selection for Egg Production in Coturnix coturnix japonica
From a randombred control population of Coturnix coturnix japonica, strains were divergently selected for high (HE) and low (LE) 120-day egg production based on individual egg records. Based on five generations of selection, realized heritabilities for HE and LE were .063 +/- .055 and .353 +/- .020, respectively.
