Table 2 Observed and predicted phenotypes, marker profiles, and segregation ratios of strawberry (F. ×ananassa) breeding parents and families at the USDA-ARS, Beltsville, MD

From: Evidence of epistatic suppression of repeat fruiting in cultivated strawberry

Breeding families 2016 No. progeny Observed parental phenotype Parental phenotype predicted by marker profile Phenotype-predicted segregation Marker-predicted segregation, single-locus model Simplest best-fit to observed segregation
