THE DIPLOID CHROMOSOME COMPLEXES OF THE PIG 173 



Text fig. 2 A graphic illustration of the total lengths of the chromosomes 

 of the spermatogonia and in different bodj- cells which have undergone various 

 degrees of fragmentation. The figures to the left refer to the length in centi- 

 meters. The dotted addition to the pillar representing the spermatogonia in- 

 dicates the greatest length found and the white line shows the minimum for 

 these cells. The heavy dotted line across the diagram represents the average 

 length of the chromosomes of somatic cells. Xote that the total lengths of the 

 somatic chromosomes fall within the limits found for the spermatogonia and 

 that the average length for these cells is almost identical t<i the spermatogonia! 

 average.
