Answer:
Acquired traits
Step-by-step explanation:
Acquired traits are those features that can be observed in the phenotype of an organism but cannot be passed on from generation to generation because they are acquired by environmental influences.
In this case, dyed hair is a non-heritable trait because this 'new' hair color is not a result of the person's DNA (alleles). Instead, it is a hair color that was acquired artificially and, therefore, cannot be passed on to the offpsring. Other examples of acquired traits could be hair length, injuries, abilities we develop or learn (riding a bicycle), scars, etc.
In contrast to acquired traits, inherited traits are those that are coded in our DNA and are passed on from generation to generation. For example, eye color, height, hair color, etc.
