Eight-strain diallel from establishment of Collaborative Cross - Blood composition, blood pressure, plasma chemistries, electrocardiography, densiometry and body composition


The classic diallel takes a set of parents and produces offspring from all possible mating pairs. Phenotype values among the offspring can then be related back to their respective parentage. When the parents are diploid, sexed, and inbred, the diallel can characterize aggregate effects of genetic background on a phenotype, revealing effects of strain dosage, heterosis, parent of origin, epistasis, and sex-specific versions thereof. We present a data set of 48 phenotypes collected from an incomplete eight-strain diallel that arose serendipitously from the establishment of the Collaborative Cross (Churchill et al. 2004; Chesler et al. 2008; Collaborative Cross Consortium 2012).


We collected data on multiple phenotypes in a diallel of eight inbred mouse strains (abbreviated names in parentheses), A/J (AJ), C57BL/6J (B6), 129S1/SvImJ (129), NOD/LtJ (NOD), NZO/H1LtJ (NZO), CAST/EiJ (CAST), PWK/PhJ (PWK), and WSB/EiJ (WSB), which are the founder strains of the Collaborative Cross.
