Probably, applied genetics' most impacts on society are as a result of genetic tests. In general, genetic tests seek to detect some feature of a person's genetic constitution. This feature can be a disease causing mutation or a marker DNA sequence used to detect presence of another gene. Obviously these procedures used for testing the status of DNA, RNA or chromosomes are included in genetic tests. What is more it is possible to include some protein based tests and classical medical examinations when they aim to detect inheritance of a trait.
