Draw a pair of homologous chromosomes as they would be matched
during prophase I if they had a paracentric inversion. (be sure to
give yourself plenty of space so drawing is clear) Let the original
gene order on these chromosomes be: L, M, N, centromere, O, P, Q,
R, S, T. Let one of the chromosomes contain an inversion that
includes P, Q, and R. Remember that the chromosomes are duplicated
at this time, and thus contain sister chromatids.
