用法筆記
Recombination is a core concept in genetics and biology. It is the biological mechanism that ensures no two individuals (except identical twins) inherit exactly the same genetic makeup. In classrooms and textbooks, it is most often discussed alongside meiosis and heredity. Outside of genetics, the word is rarely used in everyday conversation.
