This "concept demonstration" provides learners with a concrete example (a pair of shoes in a classroom "cell") of what homology means. The "chromosomes are like pairs of shoes" metaphor helps learners visualize the situation that exists in actual chromosomes. In order to be effective, learners should be familiar with DNA structure, the gene concept and the central dogma of genetics.
