A diploid cell with three pairs of homologous chromosomes is shown on the left. Each letter represents an allele of a gene on each chromosome. A cell that is some version of the diploid cell is shown on the right. The dotted line in this diagram represents the metaphase plate. When more than one cell would be present as a result of mitosis or meiosis, only one representative cell is shown. Assume no crossing-over occurred.
