Question

Which of these best describes genetic drift?

A) The movement of alleles between population
B) Random fluctuations in the gene frequencies within a population
C) A planned method to reduce the number of inferior genes in a population
D) The combining of alleles to create more genetic variations within a population

Answer 1

it's b ramdom fluctions in the gene fequinces within a poplation

Answer 2

B) Random fluctuations in the gene frequencies within a population

Step-by-step explanation:

Genetic drift is one of the evolutionary process that deviated the population from Hardy–Weinberg equilibrium. Genetic drift refers to the change in the allele frequency of population due to chance event alone. It does not include natural selection or gene transfer. It brings out random change in allele frequency in the population. Genetic drift is more effective in a small breeding population.
