Question

epigenetic changes are generally (1 point) not heritable changes in gene structure of a population. heritable changes in genetic sequences of a population. heritable \on/off switches\ for gene sequences due to environmental factors. not heritable genetic changes that are specific to an individual.

Explanation:

Epigenetic changes are modifications that can be inherited (so "not heritable" options are incorrect). They don't change the genetic sequence (so "changes in genetic sequences" option is wrong). They act as "on/off switches" for genes due to environmental factors.

Answer:

heritable "on/off switches" for gene sequences due to environmental factors.
