Table 1 Numbers of individuals with phenotypic and marker genotype data available for training and validation per generation

From: Persistence of accuracy of genomic estimated breeding values over generations in layer chickens

  1. *Training data included only phenotypes prior to a given generation; validation data consisted of hens from that generation with genotypes and own phenotypes; these hens contributed to training data in subsequent generations; the intention was to measure all traits for the genotyped birds, therefore they had very few missing values, at most 23 missing phenotypes for a give trait for 1,563 genotyped hens.
