47. A diploid organism (2n = 8) undergoes meiosis. During meiosis I, a single pair of homologous chromosomes fails to separate, while all other chromosomes segregate normally and crossing over has already occurred during prophase I. Assuming meiosis II proceeds normally, which of the following outcomes is most accurate? (A) All resulting gametes will be polyploid. (B) Two gametes will be n + 1 and two will be n − 1. (C) Two gametes will be normal, and two will be aneuploid. (D) Genetic recombination will not occur for the affected chromosome pair. (E) Sister chromatids of the affected chromosome will remain genetically identical.
