Please answer as best as you can even without the stages :) I would really appreciate it!!

1. In what ways are the mutations described in Steps 5-6 and 7-8 different from those described in Steps 9-10 and 11-12?

2. In Steps 11-12, you saw that cystic fibrosis is caused when specific sections of both copies of chromosome 8 are deleted. On the basis of this information, do you think cystic fibrosis is a dominant or recessive trait?

3. Do all mutations result in negative effects?
