Based on this pedigree chart, what could be the reason for a disease being expressed? Assume that the circles are females, the squares are males, and the filled-in shapes are the ones infected with the disease. Image Description Generation 1: An empty female connected to an empty male with four offspring. Generation 2: An empty female connected to an empty male with four offspring. A filled male, an empty female, an empty female connected to an empty male with three offspring. Generation 3: An empty female, a filled male, an empty male, filled male connected to an empty female (they are cousins) with two offspring. An empty male, an empty female connected to an empty male with four offspring. Generation 4: In the first family, there is an empty female connected with an empty male with three offspring and an empty female. In the second family, there is an empty female, a filled male, an empty male, and a filled male connected with an empty female with four offspring. Generation 5: In the first family, there is an empty female, an empty male, and a filled male. In the second family, there is an empty female, two empty males, and a filled male.
