Textbook Question
What type or types of inheritance are consistent with the following pedigree?

Identify the affected individuals in the pedigree. In this case, the filled symbols represent affected individuals.
Observe the pattern of inheritance across generations. Note if the trait appears in every generation or skips generations.
Check if both males and females are affected equally, which might suggest autosomal inheritance, or if one sex is predominantly affected, which might suggest sex-linked inheritance.
Determine if the trait is passed from affected parents to their offspring. If affected individuals have unaffected parents, consider recessive inheritance.
Consider if the trait is passed from father to son, which would rule out X-linked inheritance, as fathers pass the Y chromosome to sons.
