A) Forensic genetics is primarily used to predict future criminal behavior.
B) Forensic genetics involves analyzing DNA evidence to identify suspects or victims.
C) Forensic genetics focuses on studying genetic diseases in the general population.
D) Forensic genetics is used to determine the age of ancient human remains.



Answer :

Answer: B) Forensic genetics involves analyzing DNA evidence to identify suspects or victims

Explanation: The field of forensic genetics revolves around using DNA evidence and genetics found at crime scenes to solve crimes and identify victims and suspects. Choice A is incorrect because DNA evidence cannot be used to predict future behavior with 100% accuracy. After all, the environment and experiences that an individual grew up in are also factors that can greatly affect behavior. Thus, forensic genetics can't be used to accurately predict criminal behavior.

Choice C is incorrect because that area of study would be more so tackled by genetic epidemiology. This field focuses on how the genetics of a population can affect their health and predisposition to disease. In addition, studying genetic diseases would not yield much information in a criminal investigation.

Choice D is incorrect because this field would be more so linked to genetic anthropology. Anthropologists would enjoy using DNA to determine evolutionary relationships between different groups of humans and track their movements across the globe. In addition, DNA and genetic material tends to be poorly preserved, and would not be a helpful indication of the age of human remains.
