INTRA-SPECIFIC DIVERSITY IN HYPNEA SPECIES (RHODOPHYTA, GIGARTINALES)

The present study considers assessment of morphometry and genetic diversity of ۲۴ populations of Hypnea. Statistical analyses indicated that characters such as algal branching in habit, size of alga and Position of tetrasporange sorus had the most important role in intera-specific variation. In both morphometry and genetic diversity analysis, grouping of the populations separated the studied species into four distinct clusters and groups but populations were spread in clusters. Analysis revealed significant genetic difference among populations and some degree of genetic admixture and gene exchange among the studied populations.
