Phenotypic effects of inbreeding

PHENOTYPIC EFFECTS OF INBREEDING

When the animals are homozygous for a no. of traits, the regularity of inheritance is assured (i.e it fixes the characteristics). Inbreeding reduces vigour is called inbreeding depression. Increased inbreeding results in

  • Reduced fertility,
  • Reduced mothering ability,
  • Reduced viability and growth rate
  • Inbreeding if accompanied by selection may increase the phenotypic uniformity.
