In the Scientific Skills Exercise, when creating a histogram for the distribution of skin color phenotypes, what does the x-axis represent?

  • A: The predicted number of offspring (out of 64).
  • B: The number of dark-skin alleles.
  • C: The different types of gametes produced by the parents.
  • D: The genotypes of the offspring.

Explanation

Step 1 of 'INTERPRET THE DATA' explicitly instructs to 'put skin color as the number of dark-skin alleles along the x-axis'. This represents the different categories of the phenotypic trait being measured.
