Question

Which of the following represents the basic number of chromosomes?

• A. n
• B. 2n
• C. 4n
• D. n/2

Hint:

The basic number of chromosomes in a species is the haploid number, denoted by "n."

Answer 1

The Correct Option is A

Step 1: Understanding basic number of chromosomes.
The basic number of chromosomes refers to the number of chromosomes in a gamete (sperm or egg) and is denoted by "n." This number represents the haploid number, which is half of the diploid number (2n) found in somatic cells.
Step 2: Analyze the options.
- n: This represents the haploid number, which is the correct answer. - 2n: This represents the diploid number, which is twice the basic number of chromosomes. - 4n: This would indicate a tetraploid number of chromosomes, which is incorrect. - n/2: This does not represent a correct number of chromosomes.
Step 3: Conclusion.
The basic number of chromosomes is "n," which refers to the haploid number in a gamete.
Final Answer: \[ \boxed{n} \]
