Question
Over time, dominant alleles will tend to increase in frequency in a population.
Group of answer choices
- True
- False
Solution
Answer
True.
Over time, dominant alleles tend to increase in frequency within a population due to several factors related to natural selection, genetic drift, and the advantages these alleles may confer to the organisms that possess them. Dominant alleles can express a certain trait that may provide a survival advantage, making individuals carrying those alleles more likely to reproduce and pass them on to the next generation. Consequently, if these dominant traits are beneficial, the alleles associated with them will become more common in the gene pool over generations. Conversely, if the traits associated with dominant alleles are detrimental to survival, their frequency may decline. Overall, the dynamics of allele frequency in a population are complex and influenced by various evolutionary pressures.
