While the genotype-phenotype distinction can be seen to signify the existence of this barrier, there is a long history of researchers claiming to show ways around it most notably, the modern science of epigenetics, building on ever-increasing information about dna sequences and how genes function, shows how chemicals from outside the cell can.

A gene is a stretch of dna or rna that determines a certain trait genes mutate and can take two or more alternative forms an allele is one of these forms of a gene for example, the gene for eye color has several variations (alleles) such as an allele for blue eye color or an allele for brown eyes.

Complementation test: complementation test, in genetics, test for determining whether two mutations associated with a specific phenotype represent two different forms of the same gene (alleles) or are variations of two different genes. The expression of those genes in behavioural traits that we can measure is our phenotype phenotypes can vary because of genotypic differences and/or because the environment affects how our genes are expressed.
