Haemoglobin first appears in which stage of erythropoiesis?
Basophil erythroblast
Proerythroblast
Ohochromatic erythroblast
Polychromatophil erythroblast
Once the proerythroblast has been formed, it divides multiple times, eventually forming many mature RBCs. The first-generation cells are called basophil erythroblasts because they stain with basic dyes; the cell at this time has accumulated very little hemoglobin.
