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. Now, what about homozygous? What does it mean for individual or organism to be homozygous for some given trait? Well, there are two possibilities for this type of genotype we have an individual organism is said to be homozygous one or two cases.
