Inheritance patterns of flower colour in garden pea plant and snap dragon differ. Why is the difference observed? Explain the difference with the help of crosses in their inheritance patterns.

Explanation

To understand the differences in inheritance patterns of flower color in garden pea plants and snapdragons, we need to explore the concepts of dominance and incomplete dominance through genetic crosses.

### Step-by-Step Solution:

1. **Understanding the Concepts**:
- In garden pea plants (Pisum sativum), flower color inheritance follows the principle of dominance. This means that one allele can mask the expression of another.
- In snapdragons (Antirrhinum majus), flower color inheritance exhibits incomplete dominance, where the heterozygous phenotype is a blend of the two homozygous phenotypes.
