PLATE 12 



Influence of bone constitution on the homozygous state for achondroplasia. 

 Saluki-bassethound second generation hybrids. 



1 Litter mate brothers 1214^ (L) and 1211^ (R). No. 1214^ has inherited 

 the homozygous condition for achondroplasia on Saluki typed bone, while 1211 rf, 

 although also homozygous for achondroplasia, has inherited almost pure basset- 

 hound quality bone. 



2 Litter mate brothers 1441 <$ and 1439 <$, also both homozygous for achondro- 

 plasia. No. 1441 <$ has inherited Saluki bone type. No. 1439 ^ shows an 

 exaggerated condition of achondroplasia on thick, stocky bone type and is more 

 extreme for this condition than the bassethound.
