Options
- Aevidence from DNA from sex chromosomes only
- Bcomparison of chromosomes morphology only
- Cevidence from fossil remains, and the fossil mitochondrial DNA alone
- 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.
