Intermediate compound Cyanide Precursor compound Intermediate compound Cyanide List the genotypes that will result in each of the following phenotypes: Non-cyanogenic Slow cyanide producer Fast cyanide producer Enzyme A Enzyme B Gene A Gene B Both genes have two alleles. In each case, the dominant allele produces functional enzyme and the recessive allele produces non-functional enzyme. The precursor compound is very stable. The intermediate compound will slowly break down, producing cyanide even in the absence of enzyme B.
