Which of the following statements describes frequency-dependent selection?Multiple choice question.The fitness of a phenotype depends on the frequency of matings between individuals with that phenotype.The fitness of a phenotype depends on its frequency in the population.The fitness of a phenotype depends on the frequency of mutations leading to that phenotype
Question
Which of the following statements describes frequency-dependent selection?Multiple choice question.The fitness of a phenotype depends on the frequency of matings between individuals with that phenotype.The fitness of a phenotype depends on its frequency in the population.The fitness of a phenotype depends on the frequency of mutations leading to that phenotype
Solution
The statement that describes frequency-dependent selection is: "The fitness of a phenotype depends on its frequency in the population."
Frequency-dependent selection is a term used in evolutionary biology to describe a situation where the fitness of a phenotype is dependent on its frequency relative to other phenotypes in a population. In other words, the survival and reproduction of a phenotype is influenced by whether it is common or rare in the population.
Similar Questions
Which of the following statement accurately compares oscillating selection and frequency-dependent selection?Multiple choice question.These two types of selection are different, because in oscillating selection, the fitness of a genotype does not depend on its frequency.These two types of selection are similar because they both tend to decrease the diversity of natural populations.Frequency-dependent selection leads to an increase in diversity, while oscillating selection leads to a decrease in diversity.
