  1. 1 ab and n, abnormal and normal in phenotype, respectively.
  2. * Individuals displaying both short tail (body > tail in length) and bustling behavior were taken as abnormal.
  3. ** Significantly different from the theoretical values, assuming that the traits are inherited in an X-linked dominant manner.
