Environmental and inherited variation

Web(Variation arises through different combinations of genes inherited from the parents and through the continual mutation of genes. Some variation among individuals is not genetic, but is due to specific events or environmental influences during an organism’s life.) Why is variation important in populations? WebApr 4, 2024 · Environmental factors, as related to genetics, refers to exposures to substances (such as pesticides or industrial waste) where we live or work, behaviors (such as smoking or poor diet) that can increase an individual’s risk of disease or stressful situations (such as racism).
