Quantitative Genetics of Growth and Asymmetry

My research program has centered around quantitative genetics of growth of various morphometric characters (chiefly bone and tooth dimensions) in mice and rats. Much of this program has involved estimation of genetic and environmental components of variance and covariance for characters that has allowed a greater understanding of problems relating to growth and allometry. Much of this research has focused on assessing the genetical basis for fluctuating asymmetry (FA), the variation typically found between right and left sides of bilateral characters. FA is thought to be an excellent indicator of developmental homeostasis, and increasingly has been used to compare stability levels in populations subjected to genetic or environmental stressors such as inbreeding, hybridization, parasitic infections, pollution, and sexual selection. We have successfully used quantitative trait locus (QTL) studies to assess genetical variation in FA and related asymmetries. Most recently, I have been collaborating in investigations into the ecology and evolution of wild populations of soybeans.
