Genetic Drift

Which of the following is correct about genetic drift? I.Genetic drift is called as Sewall Wright effect II. Genetic drift increases genetic variability with in a small population IV. Genetic drift is more effective in large population

Assertion: Genetic drift refers to changes in the allele frequency occuring by chance. Reason: Sampling errors often lead to the elimination of certain alleles and fixation of others, reducing genetic variability.

Read the statements (i-iv) and choose the correct option. i. Increase in melanised moths after industrialization ii. More individuals acquiring mean character value cause disruption iii. Change in allelic frequency leads to hardy-Weinbery equilibrium iv. Genetic drift changes allelic frequency in future generations

Read the following statements and choose the correct option A. Increase in melanized moths after industrialization in Great Britain is a proof for natrual selection B. When more individuals of a population acquire a mean character value, it is called disruption C. Changes in allelic frequency in a population will lead to Hardly Weinberg equilibrium D. Genetic drift changes the existing gene ot allelic frequency in future generations

Read the following statements and select the correct option A. Increase in melanised moths after industrialisation in Great Britain is a proof for natural selection B. When more individuals of a population acquire a mean character value, it is called disruption C. Changes in allelic frequency in a population will lead to Hardy-Weinberg equilibrium D. Genetic drift changes the existing gene or allelic frequency in future generations.
