Not all Beta’s have special abilities (an ability outside of their elemental powers) special abilities is a pure blood trait.

Special abilities is a dominant trait with pure bloods because they have codominant Begavad alleles, while in Semibegas special abilities is a recessive trait because they have only one dominant Begavad allele 

Begavad abilities (their elemental powers) are dominant genes, not recessive.
