If chromosomal duplication before tetrad formation occurred twice during spermatogenesis, while the other steps of meiosis proceeded normally, which of the following would result from a single spermatocyte? a)one tetraploid sperm b) four diploid sperm c)four haploid sperm d) eight haploid sperm answer is B. I believe however, it should be C. correct me if im wrong with the following deductions. If there is one extra replication during S phase. then I went from 2N 2C -> 2N 8C. the homologous pairs should still pair up during metaphase I, and then the two daugther cells would be 1N 4C. meiosis II would leave us with 1N 2C. i would have two chromosomes yes, but of the same one.. not two different chromosomes.
