State true or false :
(i) Sexual reproduction is always biparental
(i) Sexual reproduction or may not be present in reproduction which produces variations
(iii) Most common method of reproduction in lower plants is asexual one

Explanation

### Step-by-Step Solution:

1. **Statement (i): Sexual reproduction is always biparental.**
- **Explanation:** Sexual reproduction typically involves the fusion of male and female gametes from two different parents. However, there are exceptions where a single organism can produce both types of gametes, known as hermaphrodites. Examples include certain plants like tomatoes and hibiscus. Therefore, the statement is false.
- **Conclusion:** **False**

2. **Statement (ii): Sexual reproduction may or may not be present in reproduction which produces variations.**
- **Explanation:** Sexual reproduction inherently involves genetic recombination due to the fusion of gametes, which leads to variations. Even in hermaphroditic organisms, two different gametes are produced, resulting in genetic diversity. Thus, the statement is misleading because variations are always produced through sexual reproduction.
