Asthma-Genetics

Asthma is not nessesarily considered a dominant or recessive trait. But, usually Asthma occurs when parents are sensitive to allergies or they actually have asthma. This disease is spread genetically generation from generation. This disorder is a chromosomal mutation. A gene called ADAM33 is located on chromosome 20. This is found in lung and muscle cells. This causes airways to be smaller than usual making a persons breathing more difficult.
