An аxоlоtl limb with hypоtheticаl positionаl information values 1 to 5 as shown above, is amputated at positional value 2. The blastema that forms is remoed and replaced with a regeneration blastema of value 4 from a donor albino (white) axolotl. Explain what happens as this limb regenerates. Your answer should indicate the order of positional values of the resulting limb and the origin(s) of new cells (e.g. Host (pink) vs Donor (white).
