Answer 1

2. True

6. True

Explanation:

1. Remember, the term Genetic diseases implies that they are diseases inherited genetically. Thus, environmental conditions have no direct influence on the spread of genetic diseases.

2. We can make this conclusion because research has shown that genetic disorders are more common in families with one affected member as compared to the general population. In other words, the family's medical history is part of the determinant factor.

3. Some recent studies have shown that both members of identical and fraternal twin pairs do not have the same likelihood of expressing the same genetic disease.

4. Genetic diseases do not occur at the same rate in all human populations.  Researchers often make reference to findings discovered from surviving victims of the Hiroshima nuclear bomb which is said to be the cause of some genetic diseases. Also, the sickle cell genetic disease rate of occurrence is believed to be high in Africa than in North America.

5. Scientists believe that there is no specific age of onset of genetic disease. That is to say, they may appear within an age range but not a specific age.

6. Indeed, many human and animal genetic disorders share similar characteristics . A good example is the albino genetic order in humans has been discovered to share similar characteristics that is found in animals.
