After further years of research, she has shown that the behavior is under the control of a single gene, named for (foraging). Two alleles are present, at almost equal frequencies, that is, for is polymorphic.1  for R, which is dominant; 2  for s, the recessive. innate behavior = behavior determined by the hard-wiring of the nervous system. 2  It is usually inflexible, a given stimulus triggering a given response.
