A trait is any gene-determined characteristic and is usually determined by more than one gene, therefore the exact amount depends on the specific gene. However, the number of genes in the genome varies from species to species. More complex organisms tend to have more genes. Estimates of the number of human genes, by contrast, range from 25,000 to 30,000.
