Which statement is true?

a. The production of gametes via meiosis is much simpler than mitosis because the resulting gametes only contain half as much genetic material. b. Chromatid crossover rarely results in viable zygotes because gametes lack a mechanism for lining up homologous gene sequences when this happens. c. The potential genetic variation between two zygotes is greater than the potential genetic variation between skin cells from the same organism. d. Because they are not homologous chromosomes, X and Y chromosomes do not form synaptonemal complexes during meiosis.
