Approximately 20,500 genes make up the human genome; this is only twice as many as make up the genomes of roundworms and flies.Human beings are 99.9% identical at the DNA level.Most human genes produce at least three proteins.Single gene testing (e.g.,alpha-fetoprotein)is already standardized for prenatal care.
