Answer:

  • A change in genetic variance
  • Natural selection
  • New genetic mutations
  • Linkage disequilibrium

Explanation:

Change in genetic variance :

  • Polymorphisms : Variation between individuals in a population (within species) .
  • Substitutions : Fixed variation between individuals of species (between species)

Natural Selection :

  • Those organisms best adapted to their environment have a better chance of surviving and reproducing.

New genetic mutations:

New permanent change in the base sequence of DNA.

Linkage disequilibrium:

  • Non-random assortment of allelles at 2 or more loci.
  • The closer the markers the stronger the LD , since recombination will have occured at a low rate.

All these conditions interfere with a breeder’s attempt to predict the change in a trait over many generations based on their knowledge of the trait’s heritability.
