摘要: Abstract “Outstanding” newborn rats, with parameter values more than two standard deviations above the mean (OH) or below (OL), were identified in a normal population of 720 animals and studied for correlations between these parameters: body weight, brain DNA (cell number) protein. The OH on any one parameters also higher average all others, some came from litters. OL tended to be this group entire population. Such findings may facilitate search individuals. among not same as OL. causes occurrence are likely environmental genetic.
