Question

Common origin of man and chimpanzee is best shown by

• A. Dental formula
• B. Cranial capacity
• C. Binocular vision
• D. Chromosome number

Answer 1

The correct option is D Chromosome number

The chromosomes of man and chimpanzee are quite similar. The number of

chromosomes in chimpanzee is 48 and in man is 46, which reduce due to fusion of 2 chromosomes. Further, banding pattern of many chromosomes is the same in humans and apes like chimpanzee. In fact, humans and chimpanzee show only a slight difference in banding pattern in chromosome number 3 and 6.

So, the correct answer is 'Chromosome number'
