18 Questions
What type of selection removes individuals from the center of a phenotypic distribution?
Disruptive Selection
Which selection process favors traits that benefit related members of a group?
Kin Selection
What is the outcome of Sexual Selection in terms of evolutionary fitness?
Both survival and reproductive abilities
In the context of natural selection, what happens when pollinators transport pollen across a river to flowers on the other side?
Gene Flow takes place
What process leads to the elimination of pink monkeys due to the dominance of the white allele?
Natural Selection
What drives the formation of bimodal distributions in populations under Disruptive Selection?
Removal of central individuals from the gene pool
What is required for natural selection to occur within a population?
Variation in individual traits
Which scenario would NOT promote genetic drift?
Geographical isolation leading to separate populations
What happens in a bottleneck population scenario?
Surviving population has reduced gene pool
Why is variation in individual traits important for natural selection?
To allow nature to select certain traits over others
How does the founder effect contribute to genetic drift?
By reducing the gene pool of the founding group
What role does high rate of population growth play in natural selection?
It results in a struggle for limited resources
What is the main outcome of natural selection?
Change in the genetic makeup of a population
In which type of natural selection does the distribution mean remain unchanged?
Stabilizing Selection
What happens in directional selection?
It causes a shift in the distribution towards one extreme
How does reproduction contribute to natural selection?
Individuals with traits suitable for their environment reproduce more
What is the result of stabilizing selection on extreme variations?
Extreme variations become less common or lost
Why does natural selection result in changes in allele frequencies in a population?
As individuals best adapted to the environment reproduce more
Test your knowledge on genetic drift and natural selection processes. Understand how different factors influence changes in allele frequencies within a population. Explore the concepts related to Darwin's theory of evolution.
