Cells with a full set of chromosomes are referred to as diploid or 2N, whereas cells with half the chromosomes are How many replicated chromosomes are in each of these cells? At the end of meiosis I, two cells have been produced. Once the chromosomes have formed a pair, what are they called? At which stage in meiosis I do the pairs of homologous chromosomes come together? In Model 1, how many replicated chromosomes does the cell contain during prophase? What two structures make up a single replicated chromosome?
