Final answer:
Genetic traits cannot be used to distinguish Portuguese from Africans.
Step-by-step explanation:
The statement that certain genetic traits can be used to distinguish Portuguese from Africans is not factually accurate. Genetic traits cannot be used to differentiate between specific racial or ethnic groups. While there is genetic diversity within human populations, it is not appropriate or scientifically valid to use these differences to categorize or distinguish individuals based on their racial or ethnic backgrounds. It is important to understand and promote the idea that human genetic variation is a continuum that overlaps across populations and does not neatly align with commonly held racial or ethnic categories.
