Table 1 The alelle numbers and genetic diversity (He, Nei,1978) at upper and middle stations on SFS and NFS

Slope

Station Sample size No. alleles Allele (M & I) frequency Genetic diversity (He)
Station Slope
Upper 8 3(M, I & N) 0.88 0.189
SFS 0.124
Middle 11 2 (M & I) 1.00 0.058
Middle 14 1 (N) 0.00 0.000
NFS 0.109
Upper 10 3 (M,I & N) 0.50 0.218

Note: M= the most common allele
N=null
I---its product forms enzymically inactive homodimers.
