According to this figure which of the following option is incorrect?

#Unit 5. Developmental Biology
  1. OTX is a general transcription factor, and B-catenin from the maternal cytoplasm is concentrated at the vegetal pole of the egg.
  2. These transcriptional regulators are inherited by the micromeres and activate the Pmar1 gene. Pmar1 encodes a repressor of HesC.
  3. In the veg2 macromeres, where activated Pmar1 protein represses the HesC repressor, the macromere specification and signaling genes are active.
  4. In the veg2 cells, Pmar1 is not activated and the HesC gene product shuts down the skeletogenic genes; however, those cells containing Notch can respond to the Delta signal from the skeletogenic mesenchyme.
