Verified by Toppr

  • The genetic hierarchy includes means a sequential arrangement of genetic material from simple to complex.
  • Nucleotides are the combination of nitrogenous bases and phosphate which combines to form DNA which is the genetic component of a gene which is the hereditary unit.
  • The genes form the functional unit of chromosomes.
  • The chromosomes are the carrier of the hereditary unit from one generation to another in a particular individual.
  • Several individuals combine to form the population in a particular geographical area. So, the correct answer is option D.
