  • Title: [Adaptive norm and stabilizing selection for anthropometric characters at birth].
    Author: Kurbatova OL, Botvin'ev OK, Altukhov IuP.
    Journal: Genetika; 1991 Jul; 27(7):1229-40. PubMed ID: 1756958.
    Abstract:
    Analysis carried out on medical documentation containing data on several thousand healthy and affected babies has revealed patterns of differential mortality and differential morbidity for newborns and infants which allow to estimate relative risk as a function of birth weight and body length. Adaptive norm for anthropometric traits at birth was defined as the weight or length interval in which mortality/morbidity rates were lower than the overall population level. The intensity of stabilizing selection associated with birth weight calculated from these data is several times higher in the neonatal period than for the age interval 1-12 months. Neonatal mortality in more than 50% cases can be attributed to the effects of stabilizing selection associated with birth weight.
