Question

A geneticist is studying a disease trying to determine how its inherited. DNA testing was completed on three generations of a family and a pedigree chart below was created based on the results fell in shape means that the person has the disease a Hatfield shape mean that the person carries the gene for the disease but does not have the disease males are often affected then females females tend to be carriers what term is the type of inheritance is this

Answer 1

X-linked recessive inheritance

Step-by-step explanation:

Since the disease is primarily present in males vs females, it is a s.ex linked disease.

In X-linked recessive inheritance, males tend to get disease b/c they only have one x (the other is y) which means if they get the bad "x" copy from mom then they definetely will get the disease.

Females can be carriers b/c they are XX. If they get a good copy from mom and suppose a bad copy from dad, they can still be healthy b/c the good copy is dominant. They will be carriers (cuz they have the bad copy) but themselves wont have the disease.
