Table 3 Inbreeding regression coefficients for the morphological traits and defects analysed in the PRE horse

From: Genetic inbreeding depression load for morphological traits and defects in the Pura Raza Española horse

  \({{\varvec{F}}}_{3}\) \({{\varvec{F}}}_{6}\) \({\varvec{F}}\) \(\Delta {\varvec{F}}\)
Height of withers –1.29* –1.43* –1.97* –14.40*
Height at withers 0.56 –0.74 –6.64* –60.70*
Length of shoulder –0.36 0.28 –2.76* –14.34*
Scapular-ischial length –5.06* –7.87* –8.12* –71.40*
Knock knee*** –0.27 –0.37* –0.24** –2.37*
Cresty neck*** –0.63 0.30 1.21** 11.23*
  1. *Significant at p < 0.01; **significant at p < 0.05; ***only animals that present the defects were considered (classes > 1 in the scale)
  2. \({F}_{3}\) inbreeding at 3rd generation, \({F}_{6}\) inbreeding at 6th generation;\(F\) global inbreeding coefficient, \(\Delta F\) intergenerational average increase in inbreeding
