What are samples of "Outlaw Genes"
The t locus, which is described in detail in this book by Robert Trivers, is the classic 'outlaw' or 'selfish' gene.  

If a heterozygous (single) t allele is present in the paternal mouse, the t locus is evident in sperm 95% of the time.  Talk about "Breakin' the Law"!  As a locus whose main phenotype seems to be for mitotic cheating, t seems to convey little or no benefit to the other genes by way of helping the host survive.  t/t homozygotes are sterile.  Nice summary here.
