Detailed Solution

Polymorphism refers to the occurrence of multiple forms or variants of a DNA sequence within a population. While there are certain regions of the genome that are highly conserved across individuals, there are also regions that exhibit polymorphism. Examples of polymorphic regions include Variable Number Tandem Repeats (VNTRs) and Single Nucleotide Polymorphisms (SNPs). However, the degree of polymorphism can vary among individuals.

Variable Number Tandem Repeats (VNTRs) are regions of the DNA where short sequences of nucleotides are repeated in tandem, and the number of repeats can vary among individuals. The copy number of VNTRs can indeed vary not only between individuals but also among different chromosomes within the same individual.
