Inbreeding in the united states.

Introduction. Small, isolated populations are particularly subject to inbreeding, and are thus intrinsically vulnerable to extirpation (Keller and Waller 2002).Both laboratory and field studies have shown that increased inbreeding associated with small and isolated populations can strongly reduce both the variance and mean of traits that are important components of fitness, including survival ...This study examines the susceptibility to inbreeding and outbreeding depression in crosses between four WT zebrafish lines: the inbred lines AB and Tab 14, and the F1 generation of hybrid lines TuAB and TLAB. We report that mating frequency and clutch size were significantly greater in hybrid female crosses than in inbred female crosses.The effect of heterosis on maize phenotypes has been studied for decades, but its effect on the maize-associated microbiome is much less characterized.
