Answer

To solve the question "Mendel proposed _____ postulates which have been called Principles of Inheritance," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Mendel's Work**:
- Gregor Mendel is known as the father of genetics. He conducted experiments on pea plants and formulated the foundational principles of inheritance.

2. **Identifying the Number of Postulates**:
- Mendel proposed a total of three main postulates based on his experiments. These postulates are known as the Principles of Inheritance.

3. **Listing the Principles**:
- The three principles proposed by Mendel are:
- **Law of Dominance**: This principle states that in a heterozygote, one trait will conceal the presence of another trait for the same characteristic.
- **Law of Segregation**: This principle states that during the formation of gametes, the two alleles responsible for a trait separate from each other.
- **Law of Independent Assortment**: This principle states that alleles for different traits are distributed to sex cells (& gametes) independently of one another.

4. **Final Answer**:
- Therefore, Mendel proposed **three** postulates which have been called Principles of Inheritance.
