Term
Where are people who can taste PTC found? |
|
Definition
there are tasters in almost every population, but there is a wide variation. example : less than 2% of aboriginals in Taiwan, but over 40% in Bombay. Most European and European-derived populations have frequencies around 50% |

How do people who can taste PTC adapt? |
|
Definition
he bitter taste is caused by thiocyanate which is in cabbage, turnips, mustard greens and casava which lots of people eat and avoidance of bitter-tasting foods may be an advantage for tastes |

Term
What are the implications of PTC adaptation? |
|
Definition
nontasters may be more susceptible to thyroid deficiencies, nontasters have more goiters. One hypothesis explaining taster polymorphism is that persons able to reject CNS-bearing plants would reduce the degree of thyroid interference in contrast to nontasters, which could be a major advantage among populations in iodone-poor areas, helps maintain normal metabolic levels |
