Genetic drift is change of 

1. gene frequency in same generation 

2. appearance of recessive genes

3. gene frequency from one generation to next 

4. None of the above

Random genetic drift in a population probably results from   

Genetic drift operates in 

1. small isolated population

2. large isolated population

3. fast reproductive population

4. slow reproductive population

(1) Transduction

(2) Chromosomal aberrations

(3) Genetic drift

(4) Recombination

The random changes in the allele frequency occurring by chance is termed as

1. genetic variability

2. genetic drift

3. gene migration

4. mutation
