Fig. 123. English rabbits showing a dominant form of white spotting which fluctuates both somatically and gene- 

 tically. The first five figures were employed as grades 1-5 in classifying observed fluctuations. The third figure 

 (middle row, left) is close to the fancier's ideal English marking. The two rabbits shown at the top and the one ut 

 the right, bottom, were homozygous for the English pattern; the other three were heterozygous. English pattern 

 is allelomorphic to Dutch, Fig. 138.
