Pedigrees Flashcards
Male versus Female
- Males are Square (just kidding ;) – Represented by squares
* Females are represented by circles
First comes love
• A horizontal line connecting a male and female represents a marriage line (Any coupling that results in offspring is attached with this line, even if the partners are not ‘married”
Kiddies
A vertical line and bracket connect the parents to their children
Shady characters
A shaded square or circle indicates a person that possesses that trait
• A square or circle that is not shaded indicated the person does not have the trait being studied
Labeling
• In order to read a Pedigree, two numbering rules apply
– Generation- which is shown with Roman Numerals
– Individuals- which is shown with a number
• These numbers can be used to identify individuals on the pedigree. For Example, look at the pedigree and pick out: II-5
