Tutorial

Modern genetic testing is able to examine human DNA and reveal mutations in genes that can cause disease. Genetic mutations can be inherited by offspring. By comparing a human's DNA with a control sample, scientists are able to distinguish DNA mutations.

Mutation of certain genes can cause illness and disease.

 

Example:  Mutations occurring in the 16th chromosome have been linked to developmental disorders.

 

Human activities and environmental factors can increase the frequency of gene mutations.

Smoking and X-ray exposure are causes of gene mutation.

 

Ethical Concern

The privacy of genetic information is a cause for ethical concern.  If insurance companies deny someone insurance based on their genetic predisposition for certain diseases, is that ethical?
