MORPHOLOGICALLY DISTINCTIVE X CHROMOSOME IN THE FEMALE CHROMOSOME COMPLEMENT OF THE RABBIT

Abstract
Further evidence is provided to support the classification of the X chromosome of the domestic rabbit as one which is medium-sized with a sub-metacentric centromere. In female metaphase plates, one X chromosome may be easily identified by its striking heteropycnosis, smoothness of outline, thinner chromatid arms in relation to others in the complement, and peripheral or near-peripheral location. Occasionally a kink is seen midway along its long arm.
