Dominance and Epistasis may allow different genotypes to produce the same phenotype, but the relation remains simple.

Most protein-encoding genes, the synonymous rate of change is considerably higher than the nonsynonymous rate because synonymous mutations are tolerated by natural selection

Nonsynonymous mutations, on the other hand, alter the amino acid sequence of the protein and in many cases are detrimental to the fitness of the organism, so most of these mutations are eliminated by natural selection.

The amount of genetic variation by examining phenotypic variation was difficult because many traits, a complex interaction of many genes and environmental factors determines the phenotype

The amount of genetic variation in populations is commonly measured by two parameters –

1. The proportion of polymorphic loci

2. The expected heterozygosity is the proportion
