Human genome (dna) researchers have discovered that your chimpanzee are completely different than humans, sharing small dna sequence percentage the occasional variations found at a particular gene sites in human dna are of no interest to science many genes do not influence most of our traits nearly every other human is your genetically identical twin. genetic predispositions do not explain our shared human nature and our human diversity.

Option (4).

Explanation:

Human genome may be defined as the complete DNA sequence of the organism. Human genome project is the funded project that aim is to determine the human genome.

Human genome researchers has identified that human's DNA is almost similar with each other except some variable regions. The other human can be considered as the genetically identical twin of the other humans as they DNA sequences are most similar and identical with each other.

Thus, the correct answer is option (4).

a. the production of carbon dioxide through the process of photosynthesis
