#Unit 8. Inheritance Biology

Autosomal dominant 

Traits appear in both sexes with equal frequency.

Both sexes are capable of transmitting these traits to their offspring.

An affected person has an affected parent (unless the person carries new mutations). 

The trait does not skip generations.

Unaffected people do not transmit the trait. 

Example- familial hypercholesterolemia, Huntington disease, Neurofibromatosis
