Mendel enunciated principles of inheritance

Options

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

Answer

### Step-by-Step Solution:

1. **Introduction to Mendel's Work**: Gregor Mendel is known as the father of genetics. He conducted experiments on pea plants (Pisum sativum) to understand the inheritance of traits.

2. **Mendel's Laws of Inheritance**: Mendel formulated three main principles, often referred to as Mendel's Laws of Inheritance. These are:
- **Law of Segregation**: This law states that during the formation of gametes, the two alleles responsible for a trait separate from each other. Each gamete carries only one allele for each trait. This is also known as the law of purity of gametes.
- **Law of Dominance**: According to this law, in a heterozygous condition (where two different alleles are present), the dominant allele will express itself, while the recessive allele will not be expressed. The recessive trait will only be expressed if the organism is homozygous for that trait.
- **Law of Independent Assortment**: This law states that the alleles for different traits segregate independently of one another during gamete formation. This means that the inheritance of one trait will not affect the inheritance of another trait.

3. **Conclusion**: Based on Mendel's experiments and the principles he enunciated, the correct answer to the question "Mendel enunciated principles of inheritance" is option 3, which refers to the three laws mentioned above.
