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

Match column I with column II and select the correct option from the codes given below. {:("Column I","Column II"),("Mutation",(i)"Changes in population's frequencies due to chance alone"),("Gene flow",(ii)"Differences in survival and reproduction among variant individuals"),("Natural selection",(iii)"Immigration, emigration change allele frequencies"),("Genetic drift",(iv)"Source of new alleles"):}
