Developmental Homeostasis of Body Growth in Mice

Abstract

Observations were presented of variability of body weight in mice of Large and Small inbred strains and their crossbred generations at birth, weaning (28 days), and 60 days of age. During this growth period weight variability decreased with advancing age within each genetically homogeneous inbred and F1 hybrid group, but increased in the genetically heterogeneous backcross and F2 generation.
