<span>Enzymes antibodies and clotting compounds are made of proteins, in which these proteins generally exist in different forms and a common example of it are the amino acids. To add up, these enzyme antibodies aids the immune system by serving as a catalytic antibody producing a hapten molecule.</span>

9:3: 3:1  is the phenotypic ratio showing traits as black and long hair : black and short hair: chestnut and long hair: chestnut and short hair when a chestnut horse heterozygous for pacing and hair length with a hybrid horse. 
Explanation:
Dominant trait = black hair colour (BB,Bb), trotting (TT,Tt) , long hair (LL,Ll)
recessive trait = chesnut hair colour (bb), pacing gait (tt), short hair(ll)
cross between chestnut horse heterozygous for pacing and hair length will have alleles as BbLl 
alleles for hybrid horse will also be heterozygous Bb, Ll
Punnett square to show the cross:
       BL         Bl       bL         bl
BL  BBLL  BBLl     BbLL    BbLl
Bl   BBLl    BBll     BbLl      Bbll
bL  BbLL  BbLl      bbLL     bbLl
bl    BbLl  Bbll       bblL        bbll
phenotype ratio 
black and long hair : black and short hair: chestnut and long hair: chestnut and short hair
9:3: 3:1  is the phenotype ratio.
