The geometrical devic that helps in visualizing all the possible combinationsof male and female gametes is known as

Options

A. Batgeson square
B. Morgan square
C. Punnett square
D. Mendel square

Answer

To answer the question, "The geometrical device that helps in visualizing all the possible combinations of male and female gametes is known as," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**:
- The question is asking for a specific tool or method used in genetics to visualize the combinations of male and female gametes.

2. **Identifying the Tool**:
- In genetics, there is a well-known method used to predict the genotype of offspring from a cross between two parents. This method is commonly used to visualize the combinations of gametes.

3. **Recognizing the Correct Term**:
- The tool that fits this description is called the **Punnett Square**. It allows the arrangement of male and female gametes on opposite sides of a square to show all possible combinations.

4. **Historical Context**:
- The Punnett Square was developed by **Reginald C. Punnett** in the early 20th century (around 1905). It is also sometimes referred to as a checkerboard.

5. **Eliminating Other Options**:
- Other options mentioned in the transcript, such as "Bedstone Square," "Morgan Square," and "Mendel's Scope," do not serve the same purpose as the Punnett Square.
- "Bedstone Square" relates to heredity studies, "Morgan Square" pertains to gene location in chromosomes, and "Mendel's Scope" refers to Gregor Mendel, the father of genetics, but none of these are used specifically for visualizing gamete combinations.

6. **Final Answer**:
- Therefore, the correct answer to the question is the **Punnett Square**.
