Consider a comparison of two cladistic analyses aimed atreconstructing the phylogeny of a particular set of mammalianspecies. One of these studies used Y-chromosome sequences and theother used mtDNA sequences, and both studies successfully avoidedthe problems associated with homoplasy. Explain why the speciestrees estimated by these studies would likely be very similar,despite the fact that these data sets were generated by lineagehistories that do not contain ANY individuals in common(Y-chromosomes evolve thru males only, while mtDNA evolves thrufemales only)?
