The results obtained were very compatible with those described in the literature for each classificatory group. Three large, perfectly definite clusters could be observed in this tree. A cluster was formed by Balearic nonpouter breeds and the Catalan Bare Pigeon. Another cluster occupied an intermediate position and was formed by thief pouters. They shared some remarkable peculiar features that are morphologically very different from the other breeds. A third more diversified cluster was close to the Turkish Takla Tumbler, which was used as outgroup.
