Answer 2

Answer:

After the formation of zygote, further development takes place through mitosis. We know that after mitosis, the number of chromosomes in daughter cells is same as in mother cell. Due to this, number of chromosomes in embryo is same as in zygote. For the same reason, number of chromosomes in an organism is same as in zygote or embryo. So, it is clear that the chromosomes number of zygote, embryonal cells and adult of a particular organism is always constant.
