Population genetics is a field of biology that studies the genetic composition of biological populations, and the changes in genetic composition that result from the operation of various factors, including natural selection.
A gene mutation that had been well established through genetic studies was connected with an altered amino acid sequence in a protein subsequent studies identified numerous changes in hemoglobin, and each one is the consequence of a single amino acid difference. Whereas heredity is the transmission of genetic characteristics from ancestor to descendant through the genes, genetics is concerned with hereditary traits passed down from one generation to the next.
