Quantitative trait locus mapping: fishing strategy or replicable results?

abstract：:The amygdala integrates and coordinates emotional and autonomic responses. The genetics that underlie variation in amygdala structure may be coupled to variation in levels of aggression, fear, anxiety, and affiliated behaviors. We systematically quantified the volume and cell populations of the basolateral amygdala co...

abstract：:The heritability of human personality is well-established. Recent research indicates that nonadditive genetic effects, such as dominance and epistasis, play a large role in personality variation. One possible explanation for the latter finding is that there has been recent selection on human personality. To test this ...

Variation in this behavior can thus be a target for mate choice and sexual selection, and can lead to evolution. The fruit fly, Drosophila melanogaster, has well-documented complex mal...
