Shortly after the zygote is formed, it begins the processes of duplication and division. Each resulting new cell has:
seropon [69]

Answer:A. the same number of chromosomes as was contained in the zygote.

Explanation:a zygote is formed when the sperm fertilize the egg .

After fertilization,the zygote undergoes cleavage.cleavage is the mitotic Division of the cells of a zygote to produce daughter cells.

These daughter cells are called blastomere,which contains the same number of chromosomes as the parent cells.the cells formed do not grow in size but continues to divide, forming a mass of cells.

This mass may be solid at first but as cleavage continues,the cells move away from the center,leaving a fluid filled cavity in the middle (blastocoel).

The mass of cells are called blastula.
