Uberon definition : The first few specialized divisions of an activated animal egg; Stage consisting of
division of cells in the early embryo. The zygotes of many species undergo rapid cell
cycles with no significant growth, producing a cluster of cells the same size as the
original zygote. The different cells derived from cleavage are called blastomeres
and form a compact mass called the morula. Cleavage ends with the formation of the
blastula.;
