Abstract The manifestation of hybrid vigor with regard to the inheritance of body weight was established as a postweaning phenomenon in rats. Liver weight gain generally corresponded to body weight gain and also reflected hybrid vigor. The protein/DNA ratios of the chromatin from livers of inbred and heterotic hybrid male rats were found to increase with increasing age in growing rats. Hybrid chromatin had higher protein/DNA ratios throughout the age range studies. The difference between hybrids and inbreds were greatest in the early postweaning stages of growth and maturation. The RNA/DNA ratios of chromatin from livers of inbred and hybrid male rats were also found to exhibit trends within certain developmental periods.
