To interpret the above pedigree, there are some pedigree rules that you need to know.
- Squares are males, and circles are females.
- Horizontal lines connecting shapes in the middle indicate that two individuals have offspring together.
- Vertical lines indicate a parent-offspring relationship.
- Siblings are connected with a horizontal line *above* the shapes (check out Susie's brother and Susie for an example).
There is some additional information that you need for these cats.
- Susie has a pink nose (the dominant condition).
- Susie's father also has a pink nose.
- Susie's brother has a gray nose (the recessive condition).
- Susie and "Susie's 1st partner" had one kitten, and that kitten had a gray nose.
- Fred has a pink nose.
- Fred's father has a gray nose.
- Fred's mother and her parents are all homozygous dominant for pink noses.
