Noggin mutation: The mouse, one of the phenotypic consequences of Noggin mutationis mispatterning of the spinal cord, in the posterior region of the mouse embryo, suchthat in the hindlimb region the more ventral fates are lost, and the dorsal Pax3 domain isexpanded. (this experiment is not in the lectures).a. Hypothesis for why: What would be your hypothesis for why the ventral fatesare lost and dorsal fates expanded? Include in your answer the words notochord,BMP, SHH and either (or both of) surface ectoderm or lateral plate mesoderm
