State True or False.
(1) Garden pea has seven characters only.
(2) Flowers of Pisum sativum naturally show cross pollination.
(3) A true breeding line shows the stable trait inheritance.
(4) Mendel applied statisfical methods and mathematical logic for analysing the results.

Explanation

### Step-by-Step Solution:

1. **Statement 1**: "Garden pea has seven characters only."
- **Analysis**: This statement is **False**. While Mendel studied seven specific traits in garden peas (Pisum sativum), the plant itself has many more characters and traits that can be observed. The seven traits Mendel focused on were height, flower color, flower position, pod shape, pod color, seed shape, and seed color.

2. **Statement 2**: "Flowers of Pisum sativum naturally show cross pollination."
- **Analysis**: This statement is also **False**. The flowers of Pisum sativum are bisexual and primarily self-pollinating. Mendel's experiments utilized this self-pollination to maintain genetic purity.
