A mutation affecting the cytoplasmic distribution among dividing daughter cells in female meiosis prevents the normal distribution between the secondary oocyte and the polar body. Instead, two identically sized daughter cells with the same amount of cytoplasm are produced after each division while polar bodies are still designated and disintegrated. Knowing the main function of the polar body, what effect might this mutation have?
A. Embryos developed from the mutated secondary oocyte will lack the X chromosome.
B. Sperm will not be able to penetrate the egg.
C. Oocytes with abnormal chromosome numbers will result and produce zygotes with further abnormal numbers.
D. After fertilization, the zygote may not have enough organelles and nutrients to support further cell divisions.
