What type of selection that may eliminate intermediate phenotype is?
disruptive selection
How differences in genotypes cause variations in phenotypes?
Phenotypes are the traits expressed by the genotype. So, for blood type, a person can have A and i alleles (genotype). However, in the phenotype, since i is recessive, only the A will be expressed, and the person will have an A blood type.
What type of selection is this?
directional selection
If a trait shows a wide range of phenotypes it most likely is what type of allele?
single gene
What type of lava is considered intermediate composition?
andesite
What type of selection that may eliminate intermediate phenotype is?
disruptive selection
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.
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.
Type of selection that acts against individuals of an intermediate type?
disruptive
What type of selection that acts against individuals of an intermediate type?
disruptive
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 the type of selection that acts against individuals of an intermediate type?

What is type of selection that acts against individuals of an intermediate type?
ghost. dark. fire.
What natural selection called at extreme phenotype?
This type of natural selection is called directional selection and does not display a normal curve of expressed traits, but a heavy set of data to the left of the curve that indicates the direction of selection of the extreme phenotype.Disruptive selection is where two extreme phenotypes are maintained in a population. This curve looks like a two humped camel in it's expression of these extreme traits.
In what type of dominance does a hybrid express a blending of both phenotypes?
codominance
How differences in genotypes cause variations in phenotypes?
Phenotypes are the traits expressed by the genotype. So, for blood type, a person can have A and i alleles (genotype). However, in the phenotype, since i is recessive, only the A will be expressed, and the person will have an A blood type.
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.
