Approximately 20,000 to 25,000 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.
