Question

In the tobacco plant, the male gametes have twenty-four chromosomes. What is the number of chromosomes in the female gamete? What is the number of chromosomes in the zygote?

Answer 1

Chromosomes distribution in tobacco plant:

1. Chromosomes are the material that contains genetic information and are present in all cells.
2. They are located inside the nucleus of a eukaryotic cell.
3. They are a thread-like appearance.
4. The unique structure of chromosomes helps to pack DNA tightly into histone proteins to fit inside the cell and increase stability.
5. Males and females have the same number of chromosomes in their bodies.
6. Since the male gamete of the tobacco plant has 24 chromosomes, the female gamete of the same plant also has 24 chromosomes.
7. A fertilized egg is a zygote that results from the fusion of male and female gametes.
8. The number of chromosome in the zygote would be double the number present in the gamete.
9. As a result, the zygote has 48 chromosomes.
