Question

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

(a) Evidence from DNA from *** chromosomes only

(b) Comparison of chromosomes morphology only

(c) Evidence from fossil *** and the fossil mitochondrial DNA alone

(d) Evidence from DNA extracted from *** chromosomes, autosomes and mitochondria

Answer 1

Correct option (d) Evidence from DNA extracted from chromosomes, autosomes and mitochondria*

Explanation

Chimpanzee is more closely related to man than other hominoids. It is evidenced by chromosome banding pattern, DNA extracted from *** chromosomes, autosomes and mitochondria. Molecular clock based on mitochondria DNA are used to date recent events because this DNA mutates 5-10.times faster than nuclear DNA. Some similarities between human and chimpanzee are

(a) DNA matching shows human similarity with chimpanzee.

(b) There is little difference in banding pattern in chromosomes 3 and 6 in human and chimpanzee.

(c) Serum test indicates maximum homology between human and chimpanzee.
