Question

Quizplus · Accepted Answer

Epigenetic effects refer to changes in gene expression that occur without changes in DNA sequence. Premature birth can cause epigenetic changes that increase the risk for various health and developmental problems in life, including learning difficulties. The other examples listed do not necessarily involve epigenetic effects, as they may be influenced by various other factors, such as environmental or genetic factors.
