Question

what is it called when a mutation becomes a predominant trait

Answer 1

When a mutation becomes a predominant trait in a population, it is often referred to as **adaptive evolution** or **positive selection**. This process occurs when the mutation provides some advantage that increases the likelihood of survival and reproduction in a specific environment. Over time, the frequency of the mutation rises in the population through natural selection, leading to the trait becoming more common. If the trait becomes fixed in the population, meaning that it is present in almost all individuals, it can also be described as having reached **fixation**.
