What kind of evidence suggested that man is more closely related with chimpanzee than with at her hominoid apes?

Options

  1. Aevidence from DNA from sex chromosomes only
  2. Bcomparison of chromosomes morphology only
  3. Cevidence from fossil remains, and the fossil mitochondrial DNA alone
  4. Devidence from DNA extracted from sex chromosomes, autosomes and mitochondria.

Correct answer

D. evidence from DNA extracted from sex chromosomes, autosomes and mitochondria.

Step-by-step solution

Chimpanzee is more closely related to man than other hominoids. Chimpanzees are genetically closest to humans, and in fact, chimpanzees share about 98.6 % of our DNA. Some similarities between human and chimpanzee in the chromosome banding pattern in sex chromosomes, autosomes and mitochondria. There is little difference in banding pattern in chromosomes 3 and 6 in human and chimpanzee. Serum test indicate maximum homology between human and chimpanzee.
