A zygote is a fertilized egg formed by an egg and a sperm.The zygote undergoes many mitotic events as it develops into a solid ball of cells called a blastomere.Select the correct statement that describes the condition of a blastomere.
A)During the initial cleavages,there is a tremendous increase in the number of cells and the cell size of the blastomeres.
B)During the initial cleavages,there is a tremendous decrease in the number of cells and the cell size of the blastomeres.
C)During the initial cleavages,there is a tremendous increase in the number of cells coupled with a decrease in the size of the cells composing the blastomeres.
D)During the initial cleavages,there is no increase in the number of cells of the blastomere,but the size of the cells increases.

During the initial cleavages, the zygote undergoes many mitotic events and divides into many smaller blastomeres. While there is an increase in the number of cells, there is a decrease in the size of the cells composing the blastomeres. This is because the cytoplasm of the zygote is divided among the blastomeres, resulting in smaller cells. Thus, option C is the correct statement that describes the condition of a blastomere.
