Genes, units of heredity, exist in environments that determine their immediate futures. The most important influences in such environments are often host individuals’ traits and other genes. Individuals have traits according to their genes and histories. Instances of genes arise based on (usually identical) ancestor genes and their environments, and future individuals will also have traits based on their genes and histories.
