Abstract
:
The present study was designed for studying molecular variations among some Plectropomus pessuliferus, )Fowler, 1904) populations (collected from different Red Sea locations, (KSA) using two techniques, Cytochrome Oxidase I subunit 1 gene (COX1) and Restriction site associated DNA markers (RAD). The nucleotide compositions (A, T, G and C) for each evaluated Cox1 gene fragments were calculated comparing sequeces of our samples with gene bank using Blast, showed 100% similarity with Plectropomus pessuliferus and with 99% similarity with Plectropomus laevi with 6 (SNPs) differences between the two types. This result could be a base for DNA barcoding to differentiate between species. The relationships among estimated fish samples were reconstructed. Based on RAD technique, the number of SNPs was ranged from 194 to 16120. The previous results showed that the gene flow (due to migrations) value among estimated populations was high.
