1. A manipulative chromosome model to be placed on a flat surface for the study of chromosomal changes and processes which comprises:

  • from two to four limp generally cylindrical subunits representing chromosome segments, each subunit having a length of about 4 to about 8 inches and a diameter of about 1/4 to 3/8 inch;

    a first half of a contact sensitive reusable fastener affixed to one end of each subunit substantially perpendicular to the length of the subunit; and

    a second half of the fastener affixed to the second end of each subunit substantially perpendicular to the length of the subunit whereby the subunits may be placed on the flat surface and serially joined to form a simulated chromosome.
