A single nucleotide polymorphism that occurs in a non-coding and non-regulatory region of the genome is most likely to be:
Group of answer choices
A. Neutral
B.,Under positive selection
C. Under negative selection
D. Under balancing selection
Homework Answers
Answer- A SNP (single nucleotide polymorphism) is most likely to be under positive selection as it helps in many ways. For helping to serve as biological markers that help to locate a gene associated with a disease. When located in or around the coding region it also direct role in disease by affecting the gene function.
Because of its many benefits it helps in happens as a case of positive selection.

You are studying a disease that is known to be caused by a single nucleotide change in a single gene, although the effect this change ultimately has on the protein's structure and function is unknown. You have DNA samples from multiple patients that you suspect of having this disease. What is the most efficient way to test the samples for the relevant mutation? Select one: a. PCR amplification followed by Sanger DNA sequencing b. PCR amplification followed by gel electrophoresis...
