PLEASE HELP ASAP!!!! A pedigree chart is a diagram that shows how members of a family are related to one another.
It may also show which members of a family express a certain genetic trait.
In a pedigree chart, females are represented by circles and males are represented by squares. A
horizontal line between a male and a female indicates a couple with offspring, and a vertical
line connects the couple to their child or children. Siblings are denoted by branches off the
vertical line. Each separate generation is represented by a Roman numeral.
An example of a pedigree chart is shown below.
