mitosis and differentiation is somatic cell division. Fertilization is fusion of gametes . But Meiosis only helps to develop into embryo after fertilisation which is the process of cleavage.
Cleavage is a series of rapid mitotic divisions, that starts from a single-celled zygote, in which no growth occurs between divisions, resulting in the original egg's cytoplasm becoming divided up amongst more and more, smaller and smaller, blastomeres.
