A small, isolated island population of finches experiences a drastic reduction in population size due to a volcanic eruption. The surviving finches have a different average beak size compared to the original population. This change is primarily attributed to:

The process where individuals with advantageous traits are more likely to survive and reproduce is known as:

Hugo de Vries is famous for

Which population size is most susceptible to genetic drift?

In a random mating population, frequency of disease causing allele is 80%. What would be the frequency of carrier individuals in that population.

In a population of plants, flower size shows continuous variation. Plants with medium-sized flowers attract the most pollinators, resulting in higher seed production. Plants with very small or very large flowers attract fewer pollinators. Over time, what is the likely effect of this selection pressure on flower size variation within the population?

A change in allele frequencies within a population over time is best defined as:

Mutation introduces new genes into a species and brings about the changes in

Resistant varieties evolved in much lesser time because of

Modern synthetic theory is based on

Evolutionary changes does not come about at the level of individual but at the level of
