Question
The chromosome number remains constant for a particular _________
- Ecosystem
- Species
- Community
- Biosphere
Hint:
Species
The correct answer is: Species
The gametes have half the number of chromosomes. After their fusion, the zygote thus formed has a full set of chromosomes. Therefore, the numbers of chromosomes in parents and offsprings of a particular species remain constant.
