The first is that data collected from the same sample could vary greatly depending on the precise section of the small intestine used in the experiment. However, the ratios of sucrase to lactase in individual samples remained the same, meaning that the ratio of enzyme activity remained constant even in different parts of the small intestine. The sample data showed a trimodal distribution, producing three distinct data sets, each corresponding to the different genotypes. Those homozygous dominant for lactose tolerance had the highest lactase enzyme activity, heterozygotes had a medium amount of activity, and those homozygous recessive, who also showed lactose intolerance, had little or no lactase activity. The allele frequency calculated for the phenotype corresponded closely to the expected outcome of a population in Hardy-Weinberg equilibrium (Ho). This pattern is similar to that of incomplete dominance, where heterozygotes produce a third phenotype, with the lactase-related trait
