Explanations for answers to Epiactis brooding-disadvantages quiz.

There is less recruitment to the juvenile stage.  Yes.  Reproduction by this method yields far fewer potential recruits than gamete-dissemination as found in other sea anemones but, on the flip-side, survival to the juvenile stage is virtually assured.

There is limited genetic exchange.  No.  The brooding has no connection with self-fertilisation (which is, of course, potentially genetically limiting).

There is reduced potential for geographic colonisation.  Yes.  In the absence of a free-swimming larval stage, spread of the species to new habitats depends on the crawling ability of the juveniles.  The advantage for brooders, of course, is that survival of the juveniles is enhanced because they are released into the identical habitat conditions that favour survival of the parent.
