Why is it not possible to study the pattern of inheritance of traits in human beings, the same way as it is done in pea plant ? Name the alternate method employed for such an analysis of human traits.

Explanation

### Step-by-Step Solution:

1. **Understanding the Difficulty in Studying Human Inheritance:**
- In pea plants, controlled crosses can be easily performed. This means that scientists can deliberately breed plants with specific traits to observe how those traits are passed on to the next generation.
- In humans, controlled crosses are not possible due to ethical concerns and the complexity of human reproduction. We cannot manipulate human breeding in the same way we can with plants.

2. **Complexity of Traits in Humans:**
- In pea plants, typically one gene is responsible for a single trait (simple inheritance). For example, a single gene may determine flower color.
