*Significant values were obtained through one-way ANOVA between ^agroups of genotypes, ^eamong males between groups of genotypes and ^famong females between groups of genotypes.

^§Significant values were obtained through Student T-test between ^bnormotensive males and females, ^chypertensive males and females, ^dmales and females, and ^gnormotensive and hypertensive subjects.
