It's not a story the Jedi would tell you. It's a Sith legend. Darth Plagueis was a Dark Lord of the Sith, so powerful and so wise he could use the Force to influence the midichlorians to create life… He had such a knowledge of the dark side that he could even keep the ones he cared about from dying
The correct answer for this question is this one:
Given that there are 30 people, then there are 60 alleles. 10 of these people are not tasters. So, there are 20 of those 60 are t alleles. So, 40 alleles are left, but of a mix of t and T. It said in the lesson text that people who can taste this have at least one dominant gene "T". So it could either be homozygous (T,T) or heterozygous (T,t or t,T). People with homozygous recessive genes (t,t) can't taste it.
