1. What Mendel Observed:

When true-breeding parents (e.g., TT and tt) were crossed, all F1 plants showed the dominant phenotype (tall).

However, in the F2 generation, the recessive phenotype (short) reappeared in a 3:1 ratio of dominant to recessive traits.

2. Why This Supports the Law of Segregation:

This reappearance of the recessive trait confirms that the alleles segregate durin...
