Quizplus · Accepted Answer

Primary sex characteristics are reproductive organs that are directly involved in reproduction, such as the uterus, ovaries, penis, and testicles. Secondary sex characteristics are physical traits that develop during puberty but are not directly involved in reproduction, such as growth of body hair, deepening of the voice, breast development, and broadening of the hips. Epigenetic characteristics are traits that are determined by gene expression and can be influenced by environmental factors, such as diet and stress.
