Answer 1

Answer:

A. Showing the same degree of polymorphism with hair follicles

• The double helical structure of the DNA present on saliva, hair follicles, bones, blood and sperm serve as a useful took in the forensic studies.

• This can be done as the DNA from an individual’s tissue shows the same degree of polymorphism.

• These polymorphic characters are inheritable from parents to their children.
