What is the definition of polymorphic locus?

Answer 1

A polymorphism is a phenomenon that has different shapes, and locus means spot or location. In the case of abnormal EKG findings, different shapes of the various abnormal curves can indicate that the electrical signals are arising from different locations in the heart.

Answer 2

A polymorphic locus is a specific location within a genome that has multiple possible variants or alleles present in a population. These genetic variations can arise from single nucleotide differences (SNPs), insertions or deletions, or other structural changes within the DNA sequence at that location.
