Regarding mutation select how many points are correct ?
(i) Random
(ii) Discontinuous
(iii) Continuous
(iv) Directionless

Options

A. Two
B. Three
C. Four
D. Five

Answer

To solve the question regarding mutations and determine how many points are correct, let's analyze each statement one by one.

1. **Random**: Mutations occur randomly in the DNA sequence. They are not influenced by the needs of the organism, meaning they can happen at any time and in any part of the genome. This statement is correct.

2. **Discontinuous**: Mutations can lead to discontinuous variations, which means that they can result in distinct and separate phenotypic traits rather than a gradual change. This statement is also correct.

3. **Continuous**: This statement is incorrect. Mutations typically do not produce continuous variations; rather, they can lead to distinct changes in traits. Continuous variation is more associated with polygenic traits, which are influenced by multiple genes rather than single mutations.

4. **Directionless**: This statement is correct. Mutations do not have a specific direction or purpose; they occur without any predetermined outcome or goal.

Now, let's summarize the correctness of each statement:
- (i) Random: Correct
- (ii) Discontinuous: Correct
- (iii) Continuous: Incorrect
- (iv) Directionless: Correct

Thus, three out of the four statements are correct.

**Final Answer**: 3 points are correct.
