Document Summary
Bee colonies and queen reproduction: colonies have millions of workers that do not produce offspring even though they are physiologically capable of doing so. Experimenters quit the neofem2 gene in queens, it did not affect the behaviour of the queens but it dramatically affected the behaviour of the workers making them more aggressive towards each other: developmental pathway in termites is affected by the presence or absence of a particular gene in the queen of the colony. For polygenic behavioral traits, behavioral geneticists often search for a set of genes, each of which contributes a small amount to the expression of the trait of interest: when researchers conduct such searches, they are looking for what are called quantitative trait loci (qtl"s, qtl mapping is a powerful way of finding at least the general region of the genome in which quantitative trait loci reside, mapping steps, step 1.
