Author Contributions

NGM initiated and led the studies from which the data were collected. PMV and NGM conceived the main idea for this study. SEM, MARF, KIM, GZ, and BKC error-checked, cleaned, and stored genotypic and phenotypic data, estimated IBD probabilities, and performed preliminary statistical analyses. GWM supervised the storage and quality control of DNA samples and genotypes. PMV performed theoretical calculations, statistical analyses and simulation studies, and wrote the manuscript.
