| Abstract: | Playing cards dealt in pairs are used as a model of the behaviour of alleles in a gene pool, instead of using assorted beans or beads. They have the advantage of allowing sex determination to be incorporated; court cards can determine one sex, and by dominating other values produce a convenient sex ratio. Suit colour provides the simplest allele pair. Jokers can be used as rare recessive alleles (Iethals). Suits selected in advance provide unexpected allele frequencies. Other features of the pack allow open-ended discussion and more advanced work. |
