Mode+of+Inheritance


 * Mode of Inheritance**

1. You have to inherit from one's parent's gene in order to have the disease. 2. If it is only one parent affected and a normal from the other then it's a sickle cell trait - producing no symptoms or problems for most people. 3. It can neither be contracted nor passed on to another person. 4. Some people live nearly normal but others suffer from a variety of complications.

X-linked domninant and recessive - Caused by mutations in genes on the x chromosomes, - X-linked domninant is more affected on females than males but X-linked recessive is the other way around. - A father cannot pass x-linked traits to their sons, there is no male to male transmission. - the chances of passing on the disorder is between men and woman.

Autosomal domninant and recessive 1. An Autosomal domninant happens when both parents are recessive but their child is dominant, - Autosomal domninant creates a single copy of the mutated gene affecting the child with the disorder. 2. An Autosomal dominant happens when one parent is affected so it will occur in every generation of an affected family.
