Morphogenetic Homeostasis in Mice

Abstract

The incidence of 29 minor bilateral skeletal variants is analysed in three inbred strains of mice and the hybrids between them. It was found that the frequency of asymmetrical mice (i.e. those with the variant present on one side only) was less than expected on the assumption of mice with variants on two, one, and neither sides occurring at random. This represents a form of morphogenetic homeostasis.
