The genetic and environmental structure of reproduction-related variables: the case of fertility and breastfeeding.

Twin research and human genetics : the official journal of the International Society for Twin Studies - 1 Dec 2013

Colodro-Conde Lucía, Rijsdijk Frühling, Ordoñana Juan R

Abstract excerpt

Life history theory studies the evolution of traits related to reproductive fitness. Fertility and parental investment are key life history traits which, from an evolutionary standpoint, appear strongly interrelated. The aim of this work was to analyze the genetic and environmental structure and relationship of two behaviors associated with reproductive fitness: total number of offspring and mean duration of...
