FIG. 9. A LONG-HAIRED, ROUGH, BLACK-WHITE SPOT! ED GUINEA-PIG, 



1586 



Son of o 2002 (fig. 1 , pi. 1) and of V 1067, which was a spotted triple heterozygote 

 (compare fig. 4. pi. 2). We know without breeding tests that this animal is pure as regards 

 the character long coat, the recessive which it manifests. Breeding tests have established 

 the fact that it is pure also as regards the rough character, but heterozygous as regards pig- 

 mented coat, since it produces albino offspring when mated to albinos. Fanciers' name 

 for all animals of this appearance, "Broken-color" Peruvian. 



FIG. 10 A LONG-HAIRED, SMOOTH, SPOTTE D AGOUTI-REC-AND-WHITE GUINEA-PIG, O 1709. 



Son of O 2060 (fig. 5, pi. 3} and of V 1 105, a triple heterozygote (compare fig. 4, pi. 2). 

 This animal manifests two recessive coat-characters, long coat and smooth coat, in regard 

 to which it is, of course, pure, but it is heterozygous in respect to the third pair of coat- 

 characters, for it produces albino as well as pigmented offspring, when mated to albinos.
