Notes

Mapping and Phenotype information for this QTL, its variants and associated markers

J:242654

Organisms on islands often undergo rapid morphological evolution, providing a platform for understanding mechanisms of phenotypic change. The authors used house mice living on the remote Gough Island - the largest wild house mice on record - to understand the genetics of rapid skeletal evolution in nature.

Compared to a mainland reference strain from the same subspecies (WSB/EiJ), the skeleton of Gough Island mice (GI/Wisc) is considerably larger, with notable expansions of the pelvis and limbs. The GI/Wisc skeleton also displays changes in shape, including elongations of the skull and the proximal vs. distal elements in the limbs.

Several partially inbred lines of GI/Wisc mice were created through full-sib mating for four filial generations, a procedure expected to reduce within-line heterozygosity by 60% (Silver 1995). To incorporate variation segregating among GI/Wisc mice, two partially inbred GI/Wisc lines were used for intercross experiments (denoted as crosses A and B). One pair of male and female siblings from each partially inbred line was crossed with WSB/EiJ to generate four independent F2 intercrosses. A total of 1374 F2 mice were generated: 497 from cross A (WSB/EiJ x GI/Wisc = 279 and GI/Wisc x WSB/EiJ = 218) and 877 from cross B (WSB/EiJ x GI/Wisc = 494 and GI/Wisc x WSB/EiJ = 383). From this F2 population, 827 mice were used for all skeletal phenotyping and analyses: 367 from cross A (WSB/EiJ x GI/Wisc = 206 and GI/Wisc x WSB/EiJ = 161) and 460 from cross B (WSB/EiJ x GI/Wisc = 252 and GI/Wisc x WSB/EiJ = 208).

All mice were weighed to the nearest milligram every week, beginning 1 week after birth and ending at 16 weeks. Dual energy X-ray absorptiometry (DXA) was used to measure bone morphology. Digital X-ray images (Carestream Health DXS Pro 4000) were collected for 43 F1 and 827 F2 individuals and mice from the four parental strains of the cross. X-ray images were taken at three postnatal time points (5, 10, 16 weeks of age) for each animal. A dorsal and lateral X-ray image was taken of each individual. Skeletal dimensions were measured from the X-ray images using Carestream Molecular Imaging Software (Carestream Health). Measurements were chosen to capture axes of known variation across laboratory mouse strains and across species. A total of 16 measurements were used for phenotyping, including lengths and diameters of long bones, pelvis, and skull.

All mice were genotyped using the Mega Mouse Universal Genotyping Array (MegaMUGA, Geneseek, Lincoln, NE). The MegaMUGA is an Illumina array platform containing ~77,800 markers. Most of these markers are SNPs, although some are structural variants and transgenic markers. The markers are densely and relatively evenly spaced at 33 kb across the genome, found across all autosomes, sex chromosomes, and the mitochondria. Following initial screening, the cleaned genomic data included the four GI/Wisc parents of the crosses, 70 F1 individuals, 1346 F2 individuals, and 33,191 markers. In all subsequent analyses, the authors focused on

a subset of 11,833 markers that were fixed in the four GI/Wisc parents and therefore segregated as in a standard F2 intercross

between inbred lines.

Single-trait QTL analysis was performed using HaleyKnott regression on a 0.5-cM grid across the genome, as implemented in R/qtl. Analysis was conducted separately for each of the 16 skeletal traits at 5, 10, and 16 weeks with sex, mother, and observer as additive covariates.

Additional single-trait scans were performed on F2s using two different methods to control for effects of body size on each skeletal trait: (1) by using relative skeletal sizes as the traits and (2) by treating body weight as an additive covariate in the model. Relative skeletal size was calculated by dividing each skeletal trait by the cube root of body weight for each individual (trait/body weight^1/3) and is referred to as the shape ratio.

GI/Wisc mice have larger skeletons than WSB/EiJ mice across postnatal development, with all but one trait (height of the cranial vault (HCV) at 16 weeks) showing significant expansions at all three time points.

The QTL identified in this study exhibit modest, mostly additive effects, and GI/Wisc alleles are associated with larger skeletal size at most QTL. Many of these loci also colocalize with QTL for body weight. The high degree of QTL colocalization is consistent with an important contribution of pleiotropy to skeletal evolution.

A total of 208 QTL are identified across 16 skeletal traits and three time points (genome coordinates relative to GRCm38/mm10):
