The accuracy of gene flow estimates is unknown in most natural populations because direct estimates of dispersal are often not possible. 0000011083 00000 n Extensive gene exchange is generally considered to homogenize populations and counteract divergence. With sufficiently strong selection, any gene may spread to a point where it establishes a global presence. However, if gene flow does occur in tier 1 or tier 2, researchers may choose to quantify gene flow in a more natural situation or at a larger scale. Set alert. GENE FLOW IN GROUND BEETLES (COLEOPTERA: CARABIDAE) OF DIFFERING HABITAT PREFERENCE AND FLIGHT-WING DEVELOPMENT JAMES K. LIEBHERR Department ofEntomology, Comstock Hall, Cornell University, Ithaca, NY 14853-0999 Abstract. 0000002889 00000 n Gene flow is defined as a change in the genes of a particular group of plants due to the movement of pollen, seed, or live plants carrying modified DNA sequences (transgenes). 0000000987 00000 n S. WEIR Department ofStatistics, North Carolina State University, Box 8203, Raleigh, North Carolina 27695-8203 Abstract.- We presenttheoryclarifying the general behaviorofFs,-basedand Gs,-basedestimators ofgene flow, and confirm these predictions with simulations.
