Estimation of genetic parameters in two maize recurrent selection programs
… mating design was constructed to give direct estimates of additive and dominance variance in the individual populations. Fourteen sets of 4 male by 4 female matings for each of the populations were evaluated in a randomized incomplete block (Reps/Sets) experiment grown in multiple …

Issues and challenges in current generalizability theory applications in rated measurement
… blocks of fully crossed sub-datasets and then estimates variance components based on a weighted average across these sub-datasets, while the rating method forces a sparse dataset to be a fully crossed one by conceptualizing ratings as a random facet and then estimates variance components by the …

The use of carcass traits as indicators of heifer pregnancy in Angus cattle
… pregnancy have been successful, but heritability estimates are low, indicating that genetic progress is made at a slow rate through selection. Unlike reproductive traits, carcass traits such as ribeye area (REA), backfat thickness (FAT), and intramuscular fat percentage (IMF) have moderate to high …
