Question

Quizplus · Accepted Answer

Longevity genes are responsible for individuals living longer than the average lifespan. As most of Erin's blood relatives have lived to a ripe old age, it is likely that she has inherited some of these longevity genes. Susceptibility genes increase an individual's chance of developing a certain health condition, vulnerability genes make an individual more susceptible to environmental factors that can cause health problems, and mutated genes can cause genetic disorders. None of these options are likely to be responsible for Erin's longevity.
