Quizplus · Accepted Answer

Epigenetic effects refer to changes in gene expression that are not caused by changes in the DNA sequence itself, but rather modifications to the DNA or associated proteins that can be passed down to offspring. Smoking during pregnancy can cause modifications to the DNA that can affect the growth and development of the fetus, leading to low birth weight.
