WebWhat is blastomere and morula? The two-cell blastomere state, present after the zygote first divides, is considered the earliest mitotic product of the fertilized oocyte. …. When the zygote contains 16 to 32 blastomeres it is referred to as a morula. These are the preliminary stages in the embryo beginning to form. WebBy the 110-cell (late blastula) stage, the fates of most of the blastomeres become tissue-restricted, that is to say, progeny of each blastomere contribute exclusively to a single type of tissue (Fig. l a and b) (27). What are the blastula stages? An early stage of embryonic development in animals.
