Question

Frederick's father and uncle are in prison for murder. His mother has had no violent episodes but his uncle's son has already (at age 10) been in trouble for fighting in school. Draw this pedigree, assuming that the condition exists in the family.

Answer 1

replace the words with shapes: one shape for positive for the condition, one shape for negative for the condition

Answer 2

I think that female (mother) are circles and males (father) is square. if they have the "trait" or exhibit this characteristic physically, then they are shaded.

Answer 3

Yes, females are represented by circles. Thus the males are represented by squares. When either a female or male have the "trait" then they are shaded.

Answer 4
