Play with Genetics, a feature introduced in The Sims 2, was reintroduced in the fourth installation of the franchise. This feature allows players to create siblings, children, and parents of household sims. Sims created with Play with Genetics will inherit physical features from the selected sim. Unlike the past installations, players were given the ability to create genetic children of parents of the same sex.
