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. It's the organism's visual appearance, physical appearance. So the phenotype, on the other hand, describes what the organism actually looks like, the physical appearance of that organism. And because upper case T is dominant over lower case T, what that means is this particular individual, this particular plant, will, in fact, be tall, because the dominant trait always inhibits that recessive trait.
