Internal fertilization is common in chondrichthyan fishes and, as such, calls for a collection of organic actions, together with behavioral, morphological and physiological mechanisms, to make sure profitable copulation and fertilization. This quantity correlates on hand information and concepts about the improvement, reproductive morphology, functionality, and phylogeny of chondrichthyan fishes. assurance contains oogenesis, spermatogenesis, gestation, law of reproductive tract functionality, sperm garage, nutrient provision, placentation, and phylogeny. New and intriguing information is gifted together with the concept that yolk sac viviparity is the plesiomorphic nation instead of oviparity.

Explanations for this phenomenon include sex-biased dispersal, differences in genetic effective population size of the two markers, and differences in the rate at which the two markers approach equilibrium with respect to migration and genetic drift (Buonaccorsi et al. 2001). Because mtDNA is maternally inherited it often shows a strong phylogeographic signal in species in which females exhibit natal philopatry such as sea turtles (Karl et al.
