Question

multiple genotypes for human height are possible, so there are many possible variations in phenotypes. the range of phenotypes for human height in males is shown in figure 2. figure 2: range of phenotypes for human height in males some of the phenotypes for male height are identified by two distinct ranges. - range 1: 50 - 55 inches - range 2: 75 - 80 inches which choice best describes how these height ranges are represented in figure 2? range 1 represents a common phenotype, while range 2 represents a rare phenotype for male height. range 1 represents a rare phenotype, while range 2 represents a common phenotype for male height. both range 1 and range 2 represent common phenotypes for male height. both range 1 and range 2 represent rare phenotypes for male height.

Explanation:

In the given bar - graph, the y - axis represents the percentage of males. For Range 1 (50 - 55 inches) and Range 2 (75 - 80 inches), the bars corresponding to these height ranges have very low values on the percentage (y - axis). A low percentage of occurrence in a population - based graph (where the total population is represented by the sum of all bar heights) implies that these phenotypes are not commonly found.

Answer:

Both Range 1 and Range 2 represent rare phenotypes for male height.
