The unit of heredity is:
Gene
A gene is a segment of DNA carried on a chromosome that codes for a specific trait and is passed from parents to offspring. Gregor Mendel called these hereditary units 'factors', and later work by Johannsen named them genes, establishing them as the physical unit of heredity.
Genotype and phenotype describe the total genetic makeup and the observable traits respectively, and RNA is a nucleic acid that mostly acts as a messenger during protein synthesis, not as the inherited unit itself.
Hence, Gene.
