Which main change can happen in a small population that is the direct result of genetic drift? (Points : 3) Large changes in allele frequencies can occur in a short time. The Hardy-Weinberg equilibrium will not equal 1. Recessive traits always become dominant. New individuals add their genes to the gene pool.

Genetic drift is the variation in different genotypes in a small population due to certain events that produce a large change in population, such as organisms dying out. The result of this genetic drift is that large changes in allele frequencies can occur in a short time.

Answer: New individuals add their genes to the gene pool.

Genetic drift is a natural phenomena which supports evolution in this the allele frequencies of a population changes over generation.It occurs in all populations but the effect is more prominent in small populations. The selection of allele from the gene pool to be transferred to the next generation is a chance event. Genetic drift occurs when a few number of individuals establish a population. Therefore, new individuals add their genes to the gene pool is the main change that can happen in a small population that is the direct result of genetic drift.
