WitrynaAnswers (1) DNA polymorphism is the appearance of inheritable mutation in a population at high frequency. Since Inheritable mutations finally lead to evolution, … WitrynaVariable number tandem repeat (VNTR): Locations in a genome where a short sequence of nucleotides is repeated adjacent to each other. The length of such a repeat is inherited and is termed functional when it influences gene expression. For 5-HT, the 5-HTT linked polymorphic region (5-HTTLPR) is the most commonly investigated VNTR.
