Quizplus · Accepted Answer

Current estimates suggest that the human genome contains between 20,000 and 25,000 protein-coding genes, although the exact number is still not known with certainty. This number is much lower than initial expectations, as early predictions had suggested that the human genome could contain as many as 100,000 genes or more.
