P(Hypothesis): probability of the hypothesis indicated in the columns below being true given the available pedigreed data; se = standard error; ma = metacone/id area; pr = protocone/id area; pa = paracone area; hy=hypocone/id area; ea = entoconid area; UM1 = first maxillary molar; nc = not calculable.
