We have a normal phenotype for the female and an abnormal phenotype for that female. So this will express that particular disease. Now, sometimes we're also going to see shapes, either a circle or a square that are half filled, that are half colored. And whenever we see a shape that is half filled, what that means is we're dealing with a recessive trait for that particular disease. So if the disease in question is recessive, then the way that we describe heterozygous individuals for that particular trait is by using the following symbol for a woman and a square, a half filled square for a man. So this describes a heterozygous female individual that contains a dominant upper case and a recessive lowercase.
