Which is one of the early steps in the formation of both egg and sperm cells?
A. Yolk accumulation.
B. Chromosome pairing.
C. Polar body formation.
D. Unequal division of cytoplasm.
Early in meiosis sperm and egg cells replicate their homologous chromosomes then pair them up to be divided equally among the daughter cells. Polar body formation is due to unequal division of cytoplasm in egg cells only, and the one viable egg cell that remains accumulates a small amount of yolk.
