Two different enzymes both catalyze the same biochemical reaction– the conversion of precursor molecule x into pigment molecule y. Each enzyme is the gene product of a different locus. In cells with both enzymes, the flowers are red. In cells with only one of the two enzymes, the flowers are pink. In cells with neither of the two enzymes, the flowers are white. A geneticist selfs a dihybrid and counts 32 progeny.  What is the expected number of progeny that will have red flowers?
