“In a pedigree, a shaded square represents a male with a specific trait. If a male is represented by a square that is not shaded, what does this indicate? In a pedigree, a circle represents a female. If a horizontal line connects a shaded square and a circle that is not shaded, what does this tell you about the relationship between those two individuals?
