ABSTRACT

Molecular approaches in elasmobranch research have been used predominantly for phylogenetic inference or to define population structure. However, a variety of high-resolution molecular markers allow for the interpretation of complex patterns of molecular variance as well as the fast and accurate reconstruction of individual molecular profiles. Such techniques can be useful in augmenting current understanding of the reproductive biology of elasmobranchs and, where experimental or observational approaches may be difficult, can provide novel insights. The increased access and ease of utilizing molecular approaches makes the techniques and concepts discussed in this chapter useful for any elasmobranch researcher interested in the study of reproductive biology.
