 * For the gene that codes for ADH, there are 194 known classic and insertion alleles. Two alleles that are commonly used for experimentation involving ethanol toxicity and response are ADHs (slow) and ADHF (fast). Numerous experiments have concluded that the two alleles account for the differences in enzymatic activity for each, with ADHF adult flies typically having higher ADH activity than ADHs . Physically speaking, this increase in enzymatic activity between ADHS and ADHF comes from an amino acid replacement.
