Option: (5) - All of them are correct.

As the change in allele frequency causes the change in genome of the living organism inside few generations.

Explanation:

The effects of change in allele frequency:

The effect may leave the organism with the loss of some genes, while it can effect cause the loss of some of the beneficial genes inside the genome of the organism. Along with that the process can also improve the sequence of genes which are abnormal in nature.

Genetic Drift:

"The change or the evolution inside the alleles frequency of the organisms genome, which may occur due to the chance events."

As the process of genetic drift occurs inside generations, which leaves the random organisms to live.
