Blond hair types in the Southwest Pacific. A mutation of a pigmentation gene is theorized to be the cause of blondhair genotypes observed in several Southwest Pacific islands. The distribution of this mutated gene was investigated in the American Journal of Physical Anthropology (Apr. 2014). For each in a sample of 550 Southwest Pacific islanders, the effect of the mutation on hair pigmentation was measured with the melanin (M) index, where M ranges between -4 and 4. The box plots below show the distribution of M for three different genotypes—CC, CT, and TT. Identify any outliers in the data. For which genotypes do these outliers occur? CC: 3 outliers; CT: 2 outliers
