What are the answers to these 3 questions?

4. While doing a pedigree analysis of a royal family from a Pacific Island nation, you notice two parents with the same genetic disease who have four children. All four of the girls have the disease, but when they marry unaffected individuals none of the 16 grandchildren has the disease. If this disease is controlled by a single gene, then the most likely explanation would be O the disease is dominant and is only seen in homozygous dominant individuals O the disease is dominant and is seen in heterozygous or homozygous dominant individuals the disease is recessive and is only seen in homozygous recessive individuals such as the affected girls O the disease is a spontaneous mutation

Explanation / Answer

I believe the correct answers to be:

4) C) The disease is a recessive and is only seen in homozygous recessive individuals such as affected girls.

5) D) Recessive.

6) B) Use of antibiotics cause genetic drift, which creates drug resistance. I am not exactly sure about this one but all the others seems incorrect.
