An allele that reduces the fitness of organisms is found to decrease very rapidly in a population. Most likely this allele is:
1. recently mutated
2. rare
3. dominant
4. recessive

The change in allele frequencies that occurs over time within a population is called as:
1. microevolution, or adaptive evolution
2. macroevolution, or speciation
3. coevolution
4. phylogenetic evolution

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 

Which of the following is a useful tool to measure microevolution?
1. Genetic drift
2. Hardy-Weinberg equation
3. Mendelian ratios
4. Age/sex ratio

Population that experience genetic drift most commonly are:
1. isolated
2. small in number
3. mobile
4. closely adapted to their environment

Persons with sickle cell trait are resistant to severe malaria. This shows:
1. heterozygote advantage
2. heterosis
3. punctuated equilibrium
4. reverse evolution

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
