Phenotypes are determined by an interaction of genes and the environment, but the mechanism for each gene and phenotype is different. For instance, an albino phenotype may be caused by a mutation in the gene encoding tyrosinase which is a key enzyme in melanin formation. However, exposure to UV … See more In genetics, the phenotype (from Ancient Greek φαίνω (phaínō) 'to appear, show, shine', and τύπος (túpos) 'mark, type') is the set of observable characteristics or traits of an organism. The term covers the organism's See more Phenotypic variation (due to underlying heritable genetic variation) is a fundamental prerequisite for evolution by natural selection. … See more Large-scale genetic screens can identify the genes or mutations that affect the phenotype of an organism. Analyzing the phenotypes of mutant genes can also aid in determining gene function.
