The number of chromosomes found in maize is

• A. 22
• B. 20
• C. 46
• D. 45

Hint:

Chromosome number varies widely across species, and the diploid number is typically 2n.

Answer 1

The Correct Option is A

Step 1: Understanding Chromosome Count in Maize.
Maize (corn) has 20 chromosomes in its gametes, but the diploid number of chromosomes is 2n = 22. This is typical for maize, which is often used as a model organism in plant genetics.
Step 2: Conclusion.
Thus, the correct number of chromosomes in maize is 22.
