How many genes are there in an average human?

Answer 1

Humans have 23 pairs of chromosomes. 22 pairs are homologous (basically same shape) and the last pair is known as the X and Y sex-determining chromosomes. You were correct that 23 come from mom and the other 23 from dad.

With regard to the question about genes, scientists finished sequencing the human genome in 2003. They found that the genome contained only 20,000-25,000 genes. You can read more about it if you search for human genome project on the net.

Answer 2

Genes only make up about 3% of the human genome. These are the parts that code for a functional product (such as a protein). Parts of DNA that do not code for anything are not genes.

The exact number of genes is still debated, but the current estimate for the number of human genes is 20,000-25,000.

Answer 3

The human genome project revealed that there are approximately 30,000 genes in each human somatic cell.

Answer 4

30,000 to 40,000 genes

Answer 5

30,000
