Hatchling Sceloporus occidentalis from the same dam had more similar sprint speeds than did hatchlings from different dams. Families (e.g. siblings from the same dam) of hatchlings differ significantly in body size. However, family differences in sprint speed remain significant when the size differences are removed statistically. Genetic differences among the families of lizards may account for most of the family differences in speed, although environmental or maternal effects may also contribute to family differences in sprint speed.
