What does genetic screening aim to determine?

Genetic screening primarily aims to identify the presence of inherited diseases within an individual or a population. This process involves testing for specific genetic markers or mutations that are linked to hereditary conditions. By determining whether an individual carries genes associated with certain diseases, genetic screening can help with early diagnosis, preventative health measures, and informed decision-making regarding family planning and treatment options.

The focus is on understanding genetic predispositions to diseases that may not yet manifest but could pose health risks later in life. Thus, the correct answer highlights the critical role of genetic screening in the detection of inherited health issues, enabling proactive healthcare strategies.
