The offspring from selective breeding are expected to combine the desirable traits of the two parents and thus, appear better than each of the parents.

It is the enterocoely from which the   coelom of  Deuterostom starts emerging and growing.  

Chordata, Echinodermata, Hemichordata are the classes of deuterostomes:. The zygote is the one that gets developed first in  protostomes and deuterostomes.Radial cleavage occurs in deuterostom in which the division of cells lies either in parallel direction or in perpendicular direction with respect to the polar axis.
