PURPOSE: A human chromosome model learning tool is provided to enhance an educational effect by learning assembly, disassembly, and order arrangement in various manners. CONSTITUTION: A chromosome model(10) includes 23 pairs of elementary chromosomes(11) and a plurality of additional chromosomes (12). A main body(20) includes a chromosome arrangement plate(21) and a reception part(22). The chromosome arrangement plate is formed with an inner circle(211) having a constant size and an outer circle(212) having a constant size. The outer circle is formed with 23 sections which are radially formed around a center of a circle. A chromosome number(214) is expressed in the chromosome arrangement plate. The reception part is formed to receive the additional chromosomes. A selection switch(32) selects information stored in visual data. A display unit(40) displays the visual data selected through the selection switch. A control unit controls an output of the display unit.
