Organisms that are homozygous dominant and those that are for a trait controlled by simple dominance have the same phenotype?
Because the dominant gene always appears in the phenotype, whether or not it is "pure" (homozygous) or "mixed" (heterozygous). The recessive gene does what it says: it is recessive to the dominant gene. So, if it comes between the two, the dominant always appears.
Of course, this only happens in your average Dominant-Recessive traits.

When traits are inherited in an incomplete dominance pattern what is true about the phenotype of the heterozygotes?
A trait that exhibits incomplete dominance, is one in which the heterozygous offspring will have a phenotype that is a blend between the two parent organisms. An example of this is when a homozygous red sweet pea flower crossed with a homozygous white sweet pea flower, their offspring will be heterozygous and have the pink phenotype, rather than either red or white.
True or false the phenotype of the herozygote is intermediate of for incomplete dominance?
True. In incomplete dominance, the heterozygote exhibits an intermediate phenotype that is a blend of the two homozygous phenotypes. This is different from complete dominance, where the dominant allele completely masks the expression of the recessive allele in the heterozygote.
What is similar because the heterozygous phenotype is different from the homozygous dominant phenotype?
Both heterozygous and homozygous dominant genotypes have the same dominant allele, resulting in a similar overall phenotype. The difference lies in the fact that heterozygous individuals have one dominant and one recessive allele, leading to a different genotype than homozygous dominant individuals who have two dominant alleles.
How is incomplete dominance expressed in phenotype?
In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
What describes organisms or genotypes that are homozygous for a specific trait that always produce offspring of the same phenotype?
Organisms or genotypes that are homozygous for a specific trait and always produce offspring of the same phenotype are said to be true breeding. This means that when bred with another organism of the same genotype for that trait, all offspring will display the same characteristic.
Is it easier to analyze genotype by observing phenotype in organisms with complete dominance or in organisms with incomplete dominance?
It is easier to analyze genotype by observing phenotype in organisms with incomplete dominance (also known as codominance), because in incomplete dominance the individual will show a specific phenotype for each situation, whether it is homozygous dominant, heterozygous, or homozygous recessive. For example, in flowers, such as the ones that Mendel studied, a homozygous dominant flower will be red, a homozygous recessive flower will be white, and a heterozygous flower will be pink. In complete dominance, a heterozygous will only express the dominant phenotype, as opposed to incomplete dominance, in which a heterozygous individual will express a phenotype that is representative of both of the dominant and recessive traits. Because heterozygous individuals in complete dominance express the dominant phenotype, it is hard to determine whether the genotype is homozygous dominant or heterozygous for the trait. Hope this helps!
How is phenotype expressed in a incomplete dominance?
It's expressed when a heterozygous phenotype is between two homozygous phenotypes.
How many alleles influence a phenotype in incomplete dominance?
A trait that exhibits incomplete dominance, is one in which the heterozygous offspring will have a phenotype that is a blend between the two parent organisms. An example of this is when a homozygous red sweet pea flower crossed with a homozygous white sweet pea flower, their offspring will be heterozygous and have the pink phenotype, rather than either red or white. So, the homozygous red flower will be red, the homozygous white flower will be white, and the heterozygous flower will be pink. So there are three possible phenotypes in incomplete dominance. There are also no dominant or recessives genotypes.
When traits are inherited in an incomplete dominance pattern what is true about the phenotype of the heterozygotes?
A trait that exhibits incomplete dominance, is one in which the heterozygous offspring will have a phenotype that is a blend between the two parent organisms. An example of this is when a homozygous red sweet pea flower crossed with a homozygous white sweet pea flower, their offspring will be heterozygous and have the pink phenotype, rather than either red or white.
And are similar because the heterozygous phenotype is different from the homozygous dominant?
Condominance and Incomplete Dominance.
What and what Are similar because the heterozygous phenotype is different from the homozygous dominant phenotpe?
Incomplete Dominance and Codominance.
Condition that exists when the heterozygous phenotype is somewhere in between the two homozygous phenotypes?
Incomplete dominance
True or false the phenotype of the herozygote is intermediate of for incomplete dominance?
True. In incomplete dominance, the heterozygote exhibits an intermediate phenotype that is a blend of the two homozygous phenotypes. This is different from complete dominance, where the dominant allele completely masks the expression of the recessive allele in the heterozygote.

The difference lies in the fact that heterozygous individuals have one dominant and one recessive allele, leading to a different genotype than homozygous dominant individuals who have two dominant alleles.
Dominance that occurs whenever the hybrid genotype produces a new intermediate phenotype?
When a heterozygous genotype (two different alleles) results in an intermediate phenotype, this is either codominance or incomplete dominance. If it is codominance, then both alleles are expressed together in the phenotype. If it is incomplete dominance, the two alleles produce a blended phenotype rather than both alleles being expressed together.
How are codominant alleles and incompletely dominant similar?
Codominance and incomplete dominance can only exist if the genotype has heterozygous alleles.
How is incomplete dominance expressed in phenotype?
In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
