Which can you physically see genotypes or phenotypes?
You can see the phenotype. A good way to remember is that a photograph is what you see. The genotype is the graphic representation of the trait.
If an offspring shows a phenotype that is intermediate between the phenotypes of the parents what is this type of inheritance?
Incomplete dominance can create offspring that display a trait not identical to either parent but intermediate to the two. One example of incomplete dominance is a red flower and a white flower crossbreed to form a pink flower.
What are three examples of phenotypes?
it is a thing
What a trait looks like is a?
Phenotypes
Characteristics such as hair color and height are called?
Characteristics such as hair color and height are called phenotypes. Phenotypes are determined by the make up of alleles in the body, known as genotypes.
When stabilizing selection acts to eliminate extremes at both ends of a range of phenotypes the frequencies of the intermediate phenotypes increase or decrease?
Increase, of course.
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.
What is the type of natural selection that favors intermediate phenotypes?
When natural selection favors the intermediate version of a characteristic, it is referred to as stabilizing selection. It is the opposite of disruptive selection.
When types of selection occurs when individuals in a population with the intermediate phenotype are selected for?
Stabilizing selection occurs when organisms with intermediate phenotypes are selected for.
What type of selection is shown when the bell curve narrows over time?
Stabilizing selection, which acts against both extreme phenotypes and favors intermediate variants. Hence the narrowing of the bell curve in the middle.
When two extreme phenotypes are selected in natural selection the intermediate phenotypes become?
Highly reduced, or, nonexistent.
Which kind of selection eliminates extreme phenotypes?
disruptive selection
Explain how stabilizing selection would affect a graph of the distribution of phenotypes for a trait?
I would make the graph narrower.
What type of selection may eliminate intermediate phenotypes?
b) disruptive selection. It
What is the 3 types of natural selection?
Stabilizing Selection-- The extremes are selected against.Example: height; mostly beings tend to the average height- not too many really short ones or really tall ones.Directional selection-- One extreme value is selected for.Example: speed; faster is always better so a population will tend to get faster over time.Disruptive selection-- The extremes are both selected for.This type of selection is not as common as the first two. Example: Prey-type animal with distinctive markings which the predators know will over time move away from the norm in both directions.
What is decontinuous variation?
Variation within a population in which few or no intermediate phenotypes fall between the extremes.
Selection occurs when the environment continually eliminates extremes at both ends of a range of phenotypes?
Stabilizing selection.
