Abstract
Hermafroditizam je pojava funkcionalnih reproduktivnih sistema oba spola u jednoj jedinki. Hermafroditi su česti među beskralježnjacima, ali ne među kralješnjacima kod kojih pojava oba spola u jednoj jedinki nije funkcionalna i naziva se interseks. Iznimka su neke vrste riba koje su prirodno hermafroditi. Ovaj seminar prolazi evoluciju reproduktivnih sistema kralješnjaka kako bi ukazao na varijabilnost i plastičnost reproduktivnih strategija kralješnjaka. Usporedbom filogenetskih skupina kralješnjaka može se primijetiti da gubitak hermafroditizma i juvenilnog interseksa prati pojava viviparije kao reproduktivne strategije. Viviparnost je posljedica specijalizacije Mullerove cijevi što navodi na zaključak da veća specijalizacija reproduktivnog sustava sprječava pojavu hermafroditizma i prelaska iz jednog spola u drugi.
Abstract (english)
Hermaphroditism is the presence of both sexes in one individual. Hermaphrodites are rare among vertebrates and the state in which more than one sex is present in one individual is not functional and is called intersex. This paper covers the evolution of reproductive modes in vertebrates to show the variability and plasticity of vertebrate reproductive strategies. By comparing phylogenetic groups of vertebrates it is apparent that the loss of hermaphroditism and juvenile intersex is followed by the emergence of vivipary as a mode of reproduction. Since vivipary is enabled by the specialization of the Mullerian duct we can conclude that with the greater specialization of the reproductive system, it is less likely that hermaphroditism will occur as a reproductive strategy.
