### Understanding Hemoglobin Variants: HgA and HgB

This diagram is a 2x2 matrix used to represent different hemoglobin (Hb) combinations. Hemoglobin, the protein in red blood cells that carries oxygen, can exist in multiple forms or variants. Two common variants are Hemoglobin A (HbA) and Hemoglobin B (HbB).

#### Diagram Explanation

The matrix has two columns and two rows:

- **Top Row:** Labelled with "HgA" in the first column and "HgB" in the second column.
- **Leftmost Column:** Labelled with "HgA" in the first row and "HgB" in the second row.

#### Matrix Layout:

- **Row 1, Column 1 (HgA, HgA):** 
  - Represents an individual with both copies of Hemoglobin A.
  
- **Row 1, Column 2 (HgA, HgB):**
  - Represents an individual with one copy of Hemoglobin A and one copy of Hemoglobin B.
  
- **Row 2, Column 1 (HgB, HgA):**
  - Represents an individual with one copy of Hemoglobin B and one copy of Hemoglobin A.
  
- **Row 2, Column 2 (HgB, HgB):**
  - Represents an individual with both copies of Hemoglobin B.

With this matrix, students can easily understand how different combinations of hemoglobin variants can be present in individuals. This is particularly useful in genetics and biochemistry lessons when studying inherited traits and protein functions.
