The poky phenotype is passed down cytoplasmically, which means it is inherited from the mother only. Option D suggests that a wild type female (who does not carry the cytoplasmic mutation) mated with a wild type male (who also does not carry the cytoplasmic mutation) produces half of the offspring that are poky. This is not possible because the poky phenotype is only passed down from the mother, and a wild type female cannot carry the cytoplasmic mutation. Therefore, option D is not consistent with this type of inheritance.
