WebJul 5, 2024 · The melanocytes of wild -type (nonmutant) mice produce more pheomelanin than eumelanin. The result is a sandy -colored mouse. The mutated version of the Mc1r gene, however, triggers melanocyt es to increase the production of eumelanin, resulting in the dark coat -color phenotype. WebAn organism's genotype is the set of genes that it carries. An organism's phenotype is all of its observable characteristics — which are influenced both by its genotype and by the environment. So in defining evolution, we are really concerned with changes in the genotypes that make up a population from generation to generation. However,
