Question

Cystic fibrosis is a genetic disorder in which a particular gene does not make protein the way that it otherwise normally would. Given that cystic fibrosis is a genetic disorder, how would an individual most likely contract this disease?

A. a person’s parents would have to carry genetic material for cystic fibrosis within their chromosomes which could then be passed down.

B. a person’s parents would have to carry genetic material for cystic fibrosis within their chloroplasts which could then be passed down.

C. a person would have to have been exposed to environmental influences such as living next to a nuclear power plant

D. genetic disorders can be transmitted in so many ways that it is impossible to tell how a person acquired the disease.

Answer 1

The answer is A because genetic means it comes from your genes/parents genes so you know it’s either A or B because they both state something about your parents passing it to you. But you know it can’t be B because chloroplasts are only in plants and A says chromosomes which are in humans and relate to genes so we know it must be A.
