Explanation:
Erythroblastosis fetalis (hemolytic disease of the newborn) is primarily caused by Rh incompatibility. It occurs when an Rh-negative mother carries an Rh-positive fetus. During the first pregnancy, fetal Rh+ red blood cells may enter the mother's circulation, prompting her to produce anti-Rh antibodies. In subsequent pregnancies with an Rh+ fetus, these antibodies cross the placenta and destroy the fetal red blood cells, causing severe anemia and jaundice.

Explanation:
During telophase, the chromatids reach the poles, decondense, and the nuclear envelope reassembles around each set, forming two daughter nuclei. The spindle disappears. Prophase involves nuclear envelope breakdown, metaphase aligns chromosomes, and anaphase separates chromatids. Cytokinesis often overlaps with telophase, dividing the cytoplasm.
