A morula (Latin "morus", mulberry) is an embryo at an early stage of embryonic development, consisting of approximately 4-16 cells (called blastomeres). The morula is produced by embryonic cleavage, the rapid cell division of the zygote.

Morula is a stage of embryonic development in animals, including the 16-cell phase, the 32-cell phase, and the 64-cell phase. The morula is produced by embryonic cleavage , the rapid cell division of the zygote with virtually no growth.

morula A stage in the embryonic development of some animals that consists of a solid ball of cells.
mosaic An organism whose tissues are made up of two or more genetically different types.

Because several morulas are usually transferred, multiple births are common (about 40%), and as is the case with most multiple births, the babies weigh less. To reduce the number of twins, triplets, etc.
