h e Ge ne tic Architecture
of Pollen Hoarding
Underlying the linkage of phenotypic traits is a network of genes and
developmental processes. In this chapter, I will show how genes respon-
sible for variation in anatomical, physiological, behavioral, and social
phenotypes have broad ef ects across levels and interact with each other.
In Chapters 7 and 8, I will overlay developmental process on the building
of the social phenotype.
6.1 Background
Soon at er I let h e Ohio State University and took a faculty position at
the University of California-Davis, I received a call from Greg Hunt, a
prospective graduate student. Hunt had received a master's in plant pa-
thology and was working as a technician in a plant pathology lab at the
University of Wisconsin-Madison. He was also a hobby beekeeper and
wanted to do a genetic map of the honey bee. h is was 1990: DNA marker
techniques had only recently been developed for constructing genetic
maps and used for mapping genes responsible for phenotypic traits.
h ese techniques were being applied to plants, but little had been done
with animals.
I was aware of some of the new genetic maps that had been con-
structed using restriction fragment length polymorphic (RFLP) DNA
markers. h e RFLP technique uses enzymes that cut DNA at places on
the chromosome that contain specii c nucleotide sequences, the building
