A Gene Typically Has Many Alleles Because

Question

A gene typically has many alleles because
A)humans have many traits.
B)a chromosome has many genes.
C)a DNA sequence can vary in many ways.
D)a protein sequence can vary in many ways.

Accepted Answer

The alleles of a gene refer to different versions or variations of the DNA sequence that codes for that gene. DNA sequence can vary in many ways, such as point mutations, insertions, and deletions, which can result in different alleles of a gene. Therefore, a gene typically has many alleles because of the genetic variability that can occur within a DNA sequence.
