Answer:
The correct answer is - 20000, 25,000 genes.
Explanation:
Genes are made by the functional and physical unit of the heredity called DNA. Genes are the precursors or encoded instructions to make a specific protein. Genes can be small or large depending on the DNA bases present in it which can be hundreds to millions in numbers.
According to the Human Genome Project, which found out the total genes present in a human genome between 20000 to 250000 genes approximately.
Thus, the correct answer is - 20000, 25,000 genes.
