1

Autosomal recessive

Phenotype can skip generations
Both parents must be carriers
Affects males and females

2

Autosomal dominant

Phenotype appears in every generation
Affects males and females equally

3

X-linked recessive

More males than females are affected because males with only one mutant allele are hemizygous

Transmission through unaffected carrier female
-half of sons are affected, half of daughters carriers - no daughters are affected

Transmission through hemizygous affected male
-all daughters are carries, no one affected

Transmission through affected female
-all sons will be affected and all daughters will be carriers

4

X-linked dominant

Affected males pass on the condition to all daughters by to none of their sons
Affected females with unaffected male partners pass the condition to half sons and half daughters

5

Y-linked inheritance

Male to male transmission
Males are always affected. No females affected
