Molecular Data for the Sea Turtle Population in Brazil

Table 1

Brief description of studies that reported sea turtle hybrids. Hybrid cross refers to the species that produced the hybrid, Site indicates where the hybrids were found, Analysis indicates how the hybrids were identified (mtDNA indicates the mitochondrial DNA was sequenced and scnDNA indicates that single-copy nuclear DNA was typed using RFLP), 𝑁 refers to the number of hybrids analysed in each study. A question mark indicates it was not possible to obtain the number of hybrids analysed.
