Which kind of selection eliminates extreme phenotypes?
disruptive selection
In an unchanging environment selection in a well adapted population is?
In an unchanging environment, selection in a well-adapted population is stabilizing selection. This type of selection favors individuals with intermediate phenotypes, maintaining the status quo of the population's genetic characteristics.
Which is not a way in which natural selection affects the distributions of phenotypes?
Mutation is not a way in which natural selection affects the distributions of phenotypes. Mutations introduce new genetic variations, which can then be acted upon by natural selection to influence the distribution of phenotypes within a population.
How can a wide range of phenotypes increase the chance that some individuals will survive in a changing environment?
by natural selection.
What type of selection may eliminate intermediate phenotypes?
Disruptive selection can eliminate intermediate phenotypes by favoring extreme phenotypes, leading to a bimodal distribution. This selection occurs when individuals with extreme traits have a higher fitness than those with intermediate traits, resulting in the reduction of the intermediate phenotype in the population.
Which kind of selection eliminates extreme phenotypes?
disruptive selection
Is it true or false that a natural selection acts on phenotypes not genotypes?
It doesn't. Phenotypes are viable or not in a given environment, and this influences whether the corresponding genotypes get passed on. Selection works on genotypes via the effects of their expression, their phenotype. The answer you may be looking for is that phenotypes maladapted to their environment have less babies, and pass on less copies of their genes. "Natural selection" is the whole process over generations. "Selection" may refer to misadapted bodies/phenotypes reproducing less due to illness, hunger, bad quality territories, dying earlier, etc.

Disruptive selection can eliminate intermediate phenotypes by favoring extreme phenotypes, leading to a bimodal distribution. This selection occurs when individuals with extreme traits have a higher fitness than those with intermediate traits, resulting in the reduction of the intermediate phenotype in the population.
What is Oscillating Selection?
favors different phenotypes at different times
Is it true When stabilizing selection acts to eliminate extremes at both ends of a range of phenotypes the frequencies of the intermediate phenotypes increase?
A well stated definition of what stabilizing selection is, so true.
When stabilizing selection acts to elimination extremes at both ends of a range of phenotypes the frequencies of the intermediate phenotypes increase?
Yes, when stabilizing selection is acting, individuals with extreme phenotypes are selected against, leading to an increase in the frequencies of intermediate phenotypes within a population. This process helps to maintain the overall consistency of a particular trait or characteristic over successive generations by favoring individuals with traits closer to the population average.
When two extreme phenotypes are selected in natural selection the intermediate phenotypes become?
The intermediate phenotypes tend to be selected against, resulting in stabilizing selection that favors the extreme phenotypes. This can lead to a reduction in genetic variation within the population, as individuals with intermediate traits are less likely to survive and reproduce.
Explain how stabilizing selection would affect a graph of the distribution of phenotypes for a trait?
Stabilizing selection would result in a graph showing a peak at the intermediate phenotype, with fewer individuals at the extreme phenotypes. This is because individuals with intermediate phenotypes are favored, leading to the reduction of extreme phenotypes in the population over time.
How can natural selection favor different phenotypes at different times?
Natural selection is something that happens over time and is somewhat dependent on the conditions of climate and environmental changes. There are times when natural selection can favor different phenotypes, if and when the culture starts to seek out others with certain traits and characteristics to breed.
