“…The present study offers little evidence for a maternal influence on the behavior of wild and domestic Norway rats in a novel environment. This result is in agreement with Broadhurst (1961) and Defries et al (1967) who likewise concluded that the prenatal and postnatal maternal environments account for a relatively small proportion of the total variance in open-field activity and defecation.…”

“…In general, the environmental contributions of maternal genotype had little or no effect on offspring emotionality. Defries, Thomas, Hegmann, and Weir (1967) confirmed this result by means of ovarian transplantation in 2 inbred strains of mice. Griesel (1964) reported that rats reared by inactive or active foster mothers exhibited no differences in open-field ambulation and defecation.…”

The influence of the maternal environment on the response of adult wild and domestic Norway rats to a novel environment was assessed by comparing the behavior of reciprocal hybrid groups to each other and to the parental strains. Wild rats exhibited shorter latencies for activity, greater total activity, more time grooming, smaller body weights, and larger adrenals than domestic rats. (Defecation rates were similar.) Reciprocal hybrids were intermediate to the parent strains for all variables. With the exception of total activity little evidence was obtained for a maternal influence on the behavioral responses studied. Differences between wild and domestic rats in response to a novel environment are more readily explained by genetic changes accompanying the domestication process than by differences in the maternal environments.

Newborn male DBA/2 and C57BL/6 mice were either crossfostered, fostered within strains, or, after handling, left with their own dams and compared for nine behavioral compenents observed in single animals at an adult age and for body weight measured at 4 weeks and 3 months. Many strain differences between the unfostered control groups emerged and these remained largely unchanged in comparisons between the infostered and between the outfostered groups. In neither infostered group were significant influences of fostering per se found. Some variation due to foster strain was detected mainly in the DBA outfostered group, namely, for 4-week body weight, rearing frequency, and locomotor activity, but no resemblance to the alien strain was brought about by this. Effects of litter occurred rarely. Unlike the C57BL strain, the DBAs showed a clear pattern of interdependence among exploratory acts. In spite of problems that may be attached to the crossfostering method, it was concluded that postnatal genotype-dependent maternal influences were rather unimportant as a source of variation in behavior and growth as measured between these two strains, relative to direct genetic effects and, possibly, prenatal factors.
