Influence of hone constitution on the homozygous state for achondroplasia. 

 Saluki-bassethound second generation hybrids. 



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

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

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

 hound quality bone. 



2 Litter mate brothers 1441 <$ and 1439 J 1 , also both homozygous for achondro- 

 plasia. Xo. 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.
