You Are Observing the Embryonic Development of a New Species

You are observing the embryonic development of a new species in your laboratory.This species has indeterminate development.You note a mutation in which one of the blastomeres (early cells) mutates and loses its function.What do you hypothesize would happen to this organism?

A) Nothing--the remaining blastomeres would accomodate the formation of the necessary structures of the embryo.
B) Immediate embryo death--the remaining blastomeres could not accomodate the formation of the necessary structures of the embryo.
C) Uncertain future for the embryo--depending on which blastomere was lost,the remaining blastomeres might accomodate the formation of the necessary structures of the embryo.
D) The embryo would certainly lack some features as a result of the lost blastomere.
