Question

A : The gametes will be having half the number of chromosomes as compared to non-reproductive cells.
B : A zygote will also have only half the number of chromosomes.
Which option(s) would be right?

• A. Only A is correct
• B. Only B is correct
• C. Both A and B are correct
• D. Both A and B are wrong

Answer 1

The correct option is A Only A is correct

There are special lineages of cells in specialised organs in which only half the number of chromosomes and half the amount of DNA as compared to the non-reproductive body cells are present. This is achieved by a process of cell division called meiosis. Thus, when these germ-cells from two individuals combine during sexual reproduction to form a new individual, it results in re-establishment of the number of chromosomes and the DNA content in the new generation. Therefore, the zygote will be diploid or will contain normal amount of chromosomes.
