Maternal and pup genotype contribution to growth in wild-type and tau mutant Syrian hamsters.

Abstract excerpt

The single gene mutation tau in the Syrian hamster-apart from its effect on the circadian organization of locomotor activity--has a pronounced influence on body weight. In this study we investigate the impact of maternal and pup genotypes at the tau-locus on the growth rate of pups. Homozygous tau mutant hamsters (circadian period of 20 hours) had lower growth rates and adult body weights than wild-type hamsters,...
