Pedigree analysis:
- Let statements:
	- If the trait is autosomal dominant then:
	- A = Kidney disease
	- a = No kidney disease
	- Affected genotypes: AA, Aa.
	- Unaffected genotypes: aa.
- Let statements:
	- If the trait is autosomal recessive then:
	- A = No cystic fibrosis.
	- a = Cystic fibrosis.
	- Affected genotypes: aa.
	- Unaffected genotypes: Aa, AA.
