What is cleavage nedir?

Cleavage is a term generally used in embryology to describe the successive cell divisions that occur after fertilization. It refers to the process of cell division that takes place in the early stages of the development of an embryo. These divisions result in the formation of a small ball of cells, known as a blastomere, which continue to divide and become the morula, the blastula, and ultimately, the gastrula stage of embryo development. The process of cleavage plays a vital role in the formation of the different tissues and organs that make up the organism, and errors in this process can lead to developmental abnormalities and birth defects.
