12 Questions
What does p2 represent in the Hardy-Weinberg equation?
Frequency of homozygous dominant individuals
Which phenomenon occurs when individuals at the extremes of a phenotypic range have higher fitness than those with intermediate phenotypes?
Disruptive selection
What is the purpose of the Hardy-Weinberg theorem?
To predict the frequency of genotypes in a non-evolving population
In a population under directional selection, what is expected to happen to the frequency of alleles over time?
The frequency of advantageous alleles will increase
What would disrupt the Hardy-Weinberg equilibrium in a population?
Non-random mating within the population
If disruptive selection is acting on a population, what would you expect to see in terms of phenotypes?
Extreme phenotypes being favored over intermediate phenotypes
What type of selection favours individuals at both extremes of a characteristic range?
Disruptive selection
In disruptive selection, where do individuals at the extremes of the characteristic range have more offspring compared to the rest?
At the extremes of the range
How many distinct phenotypes emerge as a result of disruptive selection?
Two
In West Africa, what are the two types of seeds available for food that are mentioned in the text?
Large and small seeds
What is the main factor influencing sexual selection?
Mating success
What is one way males may compete in sexual selection?
Competitions involving physical features to attract females
Learn about disruptive selection in natural environments, where extreme characteristics are favored over intermediate ones, leading to the emergence of two distinct phenotypes. Explore an example of disruptive selection in West Africa with two seed types available for food.
