For blood type B, the genotype is BB or BO with A as the antigens and B as antibodies. The blood type AB has the genotype to be AB. The antigens are both A & B, and no antibodies on the blood plasma. The blood type O has the genotype to be OO. There are no antigens but has antibodies to be A or B. Rhesus factor or the 'D' antigen is also found on the surface of the red blood cell. Those with it are seen to be rhesus positive or Rh+ and those without are rhesus negative or Rh-.
Dark of the Moon. The Dark of the Moon is traditionally the last three days of the Lunar cycle, immediately preceding the New Moon, and the time when the night sky is notably absent the presence of the Moon.
A week after this, the Moon is 180Â° away from the Sun, so that Sun, Earth and Moon form a line. The Moon is fully illuminated by the Sun, so this is called Full Moon. The Earth's shadow points towards the Moon at this time, but usually the Moon passes above or below the shadow and no eclipse occurs. A week later the Moon has moved another quarter of the way around the Earth, to the Third Quarter position.
