What is the primary purpose of genetic counselling?

The primary purpose of genetic counselling is to assess the likelihood of a child receiving genetic disorders from parents. This process involves evaluating the family history of genetic conditions and providing information about the risks and implications of these disorders. Genetic counsellors help prospective parents understand the inheritance patterns associated with specific genetic conditions, such as those linked to chromosome abnormalities or single-gene disorders. By discussing options available, including testing and potential interventions, genetic counselling plays a crucial role in family planning and health decision-making.

The other options provided do not align with the primary focus of genetic counselling. For instance, while genetic counselling can inform on treatment possibilities, it does not itself provide medical treatments. Similarly, investigating environmental impacts on child development and monitoring physical growth focuses on different aspects of child health and development, diverging from the specific genetic focus of counselling services.
