How did Mendel explain that it is possible that a trait is inherited but not expressed in an organism ?

Explanation

### Step-by-Step Solution:

1. **Understanding Inheritance**: Mendel's work on inheritance began with the observation of traits in pea plants. He noted that traits are passed from parents to offspring through genes.

2. **Dominant and Recessive Traits**: Mendel distinguished between dominant and recessive traits. A dominant trait is one that is expressed in the phenotype (observable characteristics) of the organism, while a recessive trait is not expressed when a dominant trait is present.

3. **Mendel's Experiment**: Mendel conducted experiments by crossing tall pea plants (dominant trait) with dwarf pea plants (recessive trait). The offspring (F1 generation) were all tall, demonstrating that the tall trait was dominant.
