In humans, a cleft chin is dominant and no-cleft is recessive. What will the generations look like? Assume that Mendel’s method of crossing two true breeding parents with opposite traits is followed. Check all that apply.

The P generation, F1 generation, and F2 generation will have all cleft chins.

The P generation, F1 generation, and F2 generation will have all no-cleft chins.

The P generation and F1 generation will have all cleft chins.

The F1 generation will have all cleft chins.

The P generation and F2 generation will have all no-cleft chins.

The P generation and F2 generation will have cleft chins and no-cleft chins.

The P generation, F1 generation, and F2 generation will have cleft chins and no-cleft chins.

Correct answers:
- The F1 generation will have all cleft chins.
- The P generation and F2 generation will have cleft chins and no-cleft chins.

Explanation: P = true-breeding cleft (CC) × true-breeding no-cleft (cc). F1 are all Cc (cleft). F2 (Cc × Cc) shows a 3:1 phenotypic ratio (cleft:no-cleft), so both phenotypes appear.
