Yes, choosing Biology, Chemistry, and Psychology at IGCSE A levels can serve as a strong foundation for a career in genetics. Biology and Chemistry are essential subjects for genetics, as they cover key areas like cell biology, molecular biology, and biochemistry, which are crucial for understanding genetic processes.

**Biology** will help you grasp the fundamental concepts of genetics, such as inheritance, DNA structure, gene expression, and genetic variation. **Chemistry** is important because genetics often involves understanding biochemical reactions and processes like DNA replication, protein synthesis, and molecular signaling. Together, these subjects provide the core scientific knowledge needed for further studies in genetics.

While **Psychology** may not be directly related to genetics, it can complement your studies, especially if you're interested in fields like behavioral genetics, neurogenetics, or genetic counseling, where understanding human behavior and mental processes plays a role.

To pursue a career in genetics, you will likely need to follow up your A levels with a degree in genetics, molecular biology, biotechnology, or a related field. This can open doors to careers in research, healthcare (such as genetic counseling), biotechnology, and personalized medicine.

With the right educational path and passion, you can certainly build a successful career in genetics.

hope this helps you!!
