Question

This figure shows a pattern of inheritance. 
The disorder shown in the figure

Quizplus · Accepted Answer

The pattern of inheritance in the figure shows that the disorder is passed down in a typical autosomal dominant inheritance pattern, where affected individuals have at least one affected parent and the disorder affects both males and females with equal frequency. This is indicated by the shaded symbols in each generation, which represent affected individuals. There is no evidence in the figure to suggest that the disorder is sex-linked, displays incomplete dominance, or results from the linkage of A and B genes.
