WebGenetic drift is a random change in allele frequency brought on by errors in random sampling. The transfer of alleles from one population to another through interbreeding or migration is known as genetic flow. These three ideas are crucial for comprehending the frequency of inherited diseases in particular populations. Step-by-step explanation WebIt is the random change in the frequency of alleles occurring by chance fluctuations. It is characterized by: (i) It is a binomial sampling error of the gene pool, i.e. that alleles which form the gene pool of the next generation are a sample of the alleles of present population.
