Cleavage is a series of rapid mitotic divisions in which the large cytoplasm of the zygote is divided into numerous smaller cells, the blastomeres (Figs. lOd-j, 12). The rate of development depends on the temperature, on the clutch and on the individual embryo. Figure 10 shows how two egg...
Given that aneuploidy of blastomeres leads to embryo mosaicism, we assumed that blastomeres of mosaic embryos do not cleave synchronously due to the different cell cycle duration of cells with varying number of chromosomes. Blastomere division synchronicity in preimplantation embryos might become an ...

- In biology, a blastomere is a type of cell produced by cell division (cleavage) of the zygote after fertilization; blastomeres are an essential part of...- development are as follows: The zygote undergoes a series of cell divisions (called cleavage) to form a structure called a morula....
