Answer 1

1. All of the above .The information that can be gaines through genome sequencing are -

• Acestry
• Drug responses
• Information about inherited disease.

2.Spontaneous mutation in germ line of one of the parent . The genes responsible for the eye colour are HER2 and OCA2 . These both genes requires each others presence to show the pigment

3.All of the above . DNA profiling has two practical applications - Paternity testing and forensic testing.

4.Pharmacogenetics
