I will, however, give one curious and complex case, not indeed as affecting any important character, but from occurring in several species of the same genus, partly under domestication and partly under nature.
Hala ere, kasu bitxi eta konplexu bat azalduko dut, ez ezaugarri inportanteren bati dagokiona delako, baizik genero bereko espezieetan gertatzen delako, aldez etxe-egoeran eta aldez natur egoeran.
