Abstract

<abstract abstract-type="main" id="jfb12490-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p id="jfb12490-para-0001">This study assessed the levels of relatedness of <italic>Galeorhinus galeus</italic> of progeny arrays using six microsatellite DNA markers. A parentage analysis from five families (mother and litter) from the North Island of New Zealand suggested the occurrence of genetic polyandry in <italic>G. galeus</italic> with two of the five litters showing multiple sires involved in the progeny arrays. This finding may be consistent with the reproductive characteristics of <italic>G. galeus</italic>, in which females can potentially store sperm for long periods of time after the mating season.</p> </abstract>
