The females are genetically the same as those of a pure race of grossulariata. Abundant experimental evidence demonstrates conclusively that not only are they themselves grossulariata, but they cannot transmit anything but the grossulariata character to their offspring. The Fn consists of grossulariata males half of which are Digitized by Microsoft®.
