A relatively new theory has arisen regarding the development of twins at fertilization. In addition to the phenomena of identical and fraternal twins, the theory suggests that semi-identical twins called polar body twins can occur if fertilization occurs in the second polar body immediately after fertilization of the oocyte (different sperm fertilizing each). If this is true, what should be true about the zygotes?
A. One twin will be physically smaller than the other after birth and later in life. B. At least one of the twins will have a genetic abnormality due to the nature of the division that produces the secondary oocyte and polar body. C. The twins will have the exact same maternal genes, but their paternal genes will vary. D. The twins will possess exactly the same genetic material.
