Now, this is what we call a genotype. The genotype of an individual or organism is simply the genetic makeup of that individual. It tells the types of genes found in that organism. And what this genotype tells us is, for this particular organism, one of the homologous chromosomes will contain a gene that is dominant, and the other one will contain a gene that is recessive. And what this tells us is the type of phenotype of that individual. So, the genotype is the genetic makeup of that individual, but the phenotype is actually what that organism will look like.
