Question
Identify the correct statement
- Chromosome number remains constant for individuals belonging to a particular species
- Chromosome number varies with individuals belonging to a particular species
- Chromosome number remains constant for all species
- All the above
Hint:
Chromosome number remains constant for individuals belonging to a particular species
The correct answer is: Chromosome number remains constant for individuals belonging to a particular species
During gamete formation, there is meiosis in which mother cell divides into 4 cells having a half number of chromosomes. In fertilization, male and female gametes fuse to form a zygote having the same number of chromosomes as parents. Hence, the number of chromosomes remains constant.
