If the haploid number of chromosomes in a plant is 12, then the number of chromosomes in monosmic is_________________?
Correct answer: D. 23
- A. 12
- B. 24
- C. 22
- D. 23
Explanation
With a haploid number of 12, the diploid number is 24; a monosomic has one chromosome fewer, so its number is 2n − 1 = 23. Therefore the correct choice is d.
