Table 2 shows an STR profile that contains seven STR locations. In this table,
the genotype frequencies, like those you calculated in the previous problems,
have been calculated for you.

3. Based on the genotype frequencies in Table 2:
a. For which STR location(s) does this individual have a common
genotype shared by more than 20% of the population?
Type your answer here.
b. For which STR location(s) does this individual have a genotype so
rare that less than 0.1% of the population share it?
Type your answer here.
