Which condition might 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?

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.

Yes he thought they should be left to chance why, because he thought that was the best thing to do
