When the population is in Hardy- Weinberg equilibrium, then the allelic frequency remains same from generation to generation, whether it is dominant or recessive in nature. This leads to maintains the frequency of dominant phenotype in a population.
Because of following reasons:
* When the population is in Hardy Weinberg equilibrium, then there is not found any selection for dominant trait. That's why the dominant phenotype do not inherently increase.
* The population size is large and there is found random mating. The random mating allows the random genotyoic individual formation. That's why the allelic frequency also remains constant. Hence the dominant phenotype don't inherently increase in a population.
* Other factors are :
No mutation and no migration are found in the population which are in Hardy Weinberg equilibrium. Hence there is found same allelic frequency. That's why there is found non inherent increase of dominant phenotype.

Which of the following statements about Hardy Weinberg equilibrium is true? a. It explains why dominant alleles do not necessarily replace recessive alleles in a population. b. It applies only to populations in which there is gene flow. c. It assumes that populations are small. d. It assumes that individuals prefer to mate with individuals with certain genotypes. e. None of the above. An answer and explanation would be greatly appreciated, thank you!
