EVOLUTION OF A POPULATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What does it mean if a population’s allele frequencies do not match the allele prediction of the Hardy-Weinberg equilibrium? (The population is not?)
A
equal
B
stabilizing
C
evolving
D
recombining
Explanation: 

Detailed explanation-1: -If any one of these assumptions is not met, the population will not be in Hardy-Weinberg equilibrium. Instead, it may evolve: allele frequencies may change from one generation to the next.

Detailed explanation-2: -If the allele frequencies change from the original frequencies after one cycle of random mating, the population is not in Hardy-Weinberg equilibrium, and evolution has occurred within the population.

Detailed explanation-3: -If observed and expected genotype frequencies are significantly different, the population is out of HWE.

Detailed explanation-4: -Comparing Generations To know if a population is in Hardy-Weinberg Equilibrium scientists have to observe at least two generations. If the allele frequencies are the same for both generations then the population is in Hardy-Weinberg Equilibrium.

Detailed explanation-5: -the frequency of the allele will be unchanged; the population will remain in Hardy-Weinberg equilibrium.
