Scientists slash estimated number of human genes
`The new estimate is 20,000 to 25,000 genes, a drop from the 30,000 to 40,000 the same group of scientists published in 2001.
By comparison, the tiny roundworm C. elegans, a favorite research subject, has around 19,500 genes. A small flowering plant in the mustard family, Arabidopsis, has about 27,000.’
