Hello james,

Genetic drift is a mechanism of evolution in which the allele frequencies change over generations as a matter of chance.

It occurs in populations of all sizes but its effect is the maximum in a small population.

Genetic drift is observed when there is a sudden decline in the population due to natural disasters (bottleneck effect), or when a new population separates from the original population to form a colony (founder effect).

Genetic drift does not take into account whether the allele is beneficial or harmful to the individual carrying it. It is possible that a beneficial allele is lost and a harmful allele persists.

HOPE THIS WILL HELP YOU

GOOD LUCK!

Hi,

Well genetic drift is just a change or variation in some genes leading to a population being genetically drifted away from the mass population. This leads to evolution becaus ethe population with more advanced genes survive and the one with no such genes die.

I hope my answer helps.

All the best.

Hello James,

Genetic drift ia a mechanism of evolution in which allele frequencies of a population change over generations due to chance. Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.

Hope this answer clears your doubt.

Thank you!
