How many genes make up the human genome

Biology
2 answers:
alisha [4.7K]3 years ago
8 0

The human genome has been estimated to have 20,000 - 25,000 human protein - coding genes. Before it was thought that the number of genes in the human genome was about 100,000, but with better and more advanced gene finding technology, this number has been revised down to the current estimate, and could continue to drop further. The human genome has 23 chromosome pairs with a total of about 3 billion DNA base pairs. There are 22 autosomal chromosomes plus the sex determining X and Y chromosomes, to make 23 pairs.

Explanation:

Species: a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding.

Population: a particular group or type of people or animals living in a place.

Gene pool: the stock of different genes in an interbreeding population.

Mutations: the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes.

Lateral Gene Transfer: the movement of genetic material between unicellular and/or multicellular organisms other than by the transmission of DNA from parent to offspring (reproduction).

Single-gene Traits: when a trait is linked to one gene-pair that consists of two alleles.

Polygenic Traits: is one whose phenotype is influenced by more than one gene.
