Monkeys and some lower groups have certain blood groups which are

Options

A. Identical to those of man
B. Identical to those of anthropods apes
C. Identical to those of anthropods apes
D. Somewhat similar to white persons

Answer

**Step-by-Step Text Solution:**

1. **Understanding Blood Groups**: Blood groups in humans and some primates, including monkeys, are classified under the ABO blood group system. This system is determined by the presence of specific antigens on the surface of red blood cells.

2. **ABO Blood Group System**: The ABO blood group system includes four main blood types:
- Type A: Presence of A antigens.
- Type B: Presence of B antigens.
- Type AB: Presence of both A and B antigens.
- Type O: Absence of both A and B antigens.

3. **Comparison with Monkeys**: Monkeys and some lower primates also exhibit the ABO blood group system. This indicates a similarity in the genetic makeup and evolutionary lineage between these species and humans.

4. **Identifying the Correct Answer**: The question asks which statement about the blood groups of monkeys and lower groups is correct. The options provided include:
- A: Identical to those of man.
- B: Identical to those of anthropoid apes.
- C: Somewhat similar to the white person.

Upon analysis, the most accurate statement is that the blood groups of monkeys and lower groups are somewhat similar to those of humans (option A).

5. **Conclusion**: Therefore, the correct answer to the question is option A: "Identical to those of man."
