In horses, Chesnut hair color is recessive to black. The pacing gait is recessive to trotting and long hair is recessive to shor

Vitek1552 [10]

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
