Animal zygotes divide to form more cells. The zygote divides itself many times by mitosis until an embryo is formed.
no
An animal embryo that has been created with animal egg and sperm. At an early stage of development, human cells are added to the embryo. The embryo will go on to develop and contain functioning human cells.
An animal will have a full set of chromosomes (2n) as an embryo.

Mitosis or cleavage

Embryo size depends upon size of animal .
