THE VICTORIA SCHOOL SANTIAGO JACOME LAB REPORT PTC BIOLOGY SL AIM: The aim of this lab is to analyze the genotype differences of classmates that are able to taste PTC‚ Thiourea and Sodium benzoate and determine the phenotypes found. Testing the ability to taste PTC has been a mainstay activity in human genetics for generations of teacher and students. The ability to taste PTC is inherited.

“Genes determine intelligence” critically discuss the contemporary evidence. Research on intelligence has been around for centuries one of the earliest known testing is said to be as early as 2200 BC where Chinese administrators tested civil servants periodically to make sure they acquired the necessary abilities/skills for their job. Today psychologist now test on weather intelligence is genetically induced and if so to what extent by taking into account environmental factors‚ using methods like
