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
