Kin selection explains how complex social behaviour can evolve at the gene level, but this theory does not identify which genes are necessary for the expression of altruism. In my first chapter I overview seven criteria for genes for altruism using the honey bee as a model species. In the second chapter I explore one criterion in detail – that altruism genes are differentially expressed between reproductive and sterile workers. I used results from previous microarray studies to reconstruct nine knowledge-based gene networks that describe reproductive altruism by means of ovary activation and de-activation. All networks were enriched for Gene Ontology ...
