Frequency of the target resistance alleles was described for different species of the An. gambiae complex and compared using statistical analysis
Freq frequency, RR homozygous resistant, RS heterozygous resistant, SS homozygous susceptible
^aAll frequencies are not significantly different
^bAll frequencies are significantly different
^cBoth frequencies are significantly different
