During spermatogenesis, the cytoplasm from the primary spermatocyte is distributed evenly between sperm cells. During oogenesis, the cytoplasm is distributed unequally. Which of the following explanations does not explain why unequal distribution of cytoplasm in oogenesis is advantageous? The egg requires more cytoplasm to protect the chromosomes. Polar bodies allow meiosis and the reduction in chromosome number to occur. The cytoplasm of the egg contains mRNA that the zygote requires during cleavage. The egg supplies almost all of the organelles required for further development if fertilization takes place so more space and cytoplasm is required.
