Abstract(s)
Reproduction by sexual or asexual viviparity is a common
phenomenon in some anemone species. In this short
communication, the origin of the brooded young of Actinia equina
and A. schmidti from the Portuguese shore was investigated. DNA
was extracted from 56 brooding adult Actinia sp. and the nuclear
gene that codes for the 28S ribosomal subunit was sequenced.
Species identity was then assessed using GenBank. In total, 50
individuals were A. schmidti, five were A. equina and one had a
hybrid origin. Three adult anemones (the hybrid, one A. equina
and one A. schmidti) possessed two different 28S sequences and
so their offspring was selected for further analysis using the same
molecular procedure. Each brooded polyp was found to possess
the exact same sequence as its parent, strongly suggesting the
asexual origin of broods in A. equina and A. schmidti.
