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
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
At a particular locus, frequency of 'A' allele is 0.6 and that of 'a' is 0.4. What would be the frequency of heterozygotes in a randomly mating population of equilibrium ?
(1) 0.16
(2) 0.36
(3) 0.48
(4) 0.24

(2) 44
(3) 48
(4) 49
If p=0.8 calculate q
(1) 0.8
(2) 0.2
(3) 6.4
(4) 0.4
If a population has dominant phenotype in 1600 individuals out of 2000 then calculate the frequency of heterozygote.
(1) 494
(2) 256
(3) 128
(4) 356
If in a given population number of individuals with dominant phenotype are 60% what will be the number of heterozygote in that population?
(1) Around 23%
(2) Around 46%
(3) 26%
(4) 25%
In a population of red (dominant) and white flowers, the frequency of red flowers is 91 %. What is the frequency of the red allele?
(1) 9 %
(2) 30 %
(3) 91 %
(4) 70 %
A change in allele frequency within a population, over a succession of generations, is called:
(1) microevolution, or adaptive evolution
(2) macroevolution, or speciation
(3) coevolution
(4) phylogenetic evolution
