Provided the first solid evidence to link a specific gene with a specific. Throughout his experiments, he provided evidence to support. Morgan utilized an accessible and ideal species for his experiments, fruit flies. After years of work he discovered a mutant phenotype. Mutant phenotype: assumed mutation to the wild phenotype. Wild phenotype: characteristic most commonly observed in natural populations.
