Genetic Drift occurs due to : 
1. Natural selection 
2. Sudden population migration 
3. Continuous gene migration 
4. Mutation 

A population will not exist in Hardy-Weinberg equilibrium if:
1. Individuals mate selectively
2. There are no mutations
3. There is no migration
4. The population is large 

A gene locus has two alleles A, a. If the frequency of dominant allele A is 0.4, then what will be the frequency of homozygous dominant, heterozygous and homozygous recessive individuals in the population?

At a particular locus, the 'A' allele frequency is 0.6 and that of 'a' allele is 0.4. What would be the frequency of heterozygotes in a random mating population at equilibrium? 

The tendency of population to remain in genetic equilibrium may be disturbed by 
1. Random mating
2. Lack of migration
3. Lack of mutations
4. Lack of random mating 

Genetic drift operates in  
1. Large isolated populations
2. Non-reproductive populations
3. Slow reproductive populations
4. Small isolated population 

Which is the most common mechanism of genetic variation in the population of a sexually reproduction organism? 
1. Transduction
2. Chromosomal aberrations
3. Genetic drift
4. Recombination 

In Hardy-Weinberg equation, the frequency of heterozygous individual is represented by 
1. 2pq
2. Pq
3. q²
4. p²
