Large-scale coding sequence change underlies the evolution of postdevelopmental novelty in honey bees.

abstract：:A parsimony analysis was performed on restriction sites at the Hba-ps4 pseudogene locus within one of four inversions associated with mouse t haplotypes. The results suggest that all t haplotypes form a monophyletic group and that the in (17)4 inversion originated before the radiation of the Mus musculus species compl...
