Verified step by step guidance

Understand the basic symbols used in pedigree charts: squares represent males, and circles represent females.

Recognize that an 'affected' individual in a pedigree is typically shown with a filled (shaded) symbol.

Recall that an open (unfilled) circle represents an unaffected female, while a filled circle represents an affected female.

Note that triangles are not standard symbols for individuals in pedigrees; they may be used for other purposes like indicating pregnancy or unknown sex.

Therefore, the symbol for an affected female is a filled circle.
