• Mother

• Father

• second cousin

The parents in this example are

• affected by the disease

• carriers of the disease

• totally normal

What are the chances that a child will inherit a recessive disorder from 2 parents who are carriers of the non-working gene?

• 1 out of 2

• 1 out of 4

• 3 out of 4

Chances are higher that 2 people would have the same recessive non-working genes if they are related.

• True

• False
