Number of genomes in a tetraploid plant having 24 chromosomes is

Options

A. 6
B. 12
C. 24
D. 4

Answer

To solve the question regarding the number of genomes in a tetraploid plant having 24 chromosomes, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Ploidy**:
- Ploidy refers to the number of sets of chromosomes in a cell. For example, diploid (2n) means there are two sets of chromosomes, while tetraploid (4n) means there are four sets.

2. **Identifying the Given Information**:
- The plant is described as tetraploid (4n) and has a total of 24 chromosomes.

3. **Calculating the Number of Chromosome Sets**:
- Since the plant is tetraploid (4n), we can determine the number of chromosomes in one set (n) by dividing the total number of chromosomes by the ploidy level:
\[ n = \frac{\text{Total Chromosomes}}{\text{Ploidy}} = \frac{24}{4} = 6 \]

4. **Understanding Genomes**:
- The term "genome" refers to the complete set of genetic material in an organism. In this case, since we calculated that n = 6, this means there are 6 genomes in the tetraploid plant.

5. **Final Answer**:
- Therefore, the number of genomes in the tetraploid plant having 24 chromosomes is **6**.
