Number of chromosomes in meiocytes of maize and apple are respectively

Options

A. 20,34
B. 34,16
C. 24,16
D. 10,17

Answer

To determine the number of chromosomes in the meiocytes of maize and apple, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Term 'Meiocyte':**
- Meiocytes are specialized cells that undergo meiosis to produce gametes. It is important to know that these cells have a specific number of chromosomes that is half of the diploid number.

2. **Identify the Chromosome Number for Maize:**
- The meiocyte of maize (Zea mays) has a haploid chromosome number of 10. Therefore, the diploid number is 20 (since diploid = 2 * haploid).

3. **Identify the Chromosome Number for Apple:**
- The meiocyte of apple (Malus domestica) has a haploid chromosome number of 17. Therefore, the diploid number is 34 (since diploid = 2 * haploid).

4. **Compile the Results:**
- Now that we have the chromosome numbers for both plants, we can summarize:
- Maize meiocytes have 20 chromosomes.
- Apple meiocytes have 34 chromosomes.

5. **Final Answer:**
- The number of chromosomes in meiocytes of maize and apple are respectively 20 and 34.
