Final answer:
The MAFs mentioned in the question refer to Minor Allele Frequencies, which are genetic variants represented by different colors. Studying these frequencies is important for understanding genetic diversity, disease susceptibility, and drug response in different populations.
Step-by-step explanation:
The MAFs mentioned in the question are abbreviations for different genetic variants known as Minor Allele Frequencies. These variants can be represented by different colors such as black, blue, and red. In genetics, these frequencies indicate the prevalence of a specific allele in a population. It is important to study them because they can have implications for understanding genetic diversity, disease susceptibility, and drug response in different populations.
