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.
When neither gene in a genotype pair is dominant and neither gene is recessive the genes are said to be .?
Incomplete dominant alleles.
When the heterozygous genotype results in a phenotype where both alleles are fully and separated expressed?
codominance.
In snapdragons the color of the flowers is controlled by incomplete dominance The teo alleles are red R and white r what is genotype of a pink snapdragon?
D
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 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.

How are codominant alleles and incompletely dominant similar?
Codominance and incomplete dominance can only exist if the genotype has heterozygous alleles.
When neither gene in a genotype pair is dominant and neither gene is recessive the genes are said to be .?
Incomplete dominant alleles.
When the heterozygous genotype results in a phenotype where both alleles are fully and separated expressed?
codominance.
What is an example of an incomplete dominance?
A good example of incomplete dominance is the color of Japanese 4 o'clock flowers. A red Japanese 4 o'clock will have the genotype RR. A white Japanese 4 o'clock will have the genotype WW.When these two flowers are crossbred, each will give one of their genes. The red flower will give a R (for red) gene. The white flower will give a W (for white) gene. The offspring will have the genotype RW.Since neither of these are recessive, (recessive genes have lower case letters) they both show up in the phenotype. The result is a mix of red and white: pink flowers!Had the white gene been recessive, and the offspring had the genotype Rw, then the flower would be red. Since both are dominant, they have incomplete control of the phenotype.

What is a trait that is a blend of a dominant and recessive gene?
It would be incomplete dominance because the two genes blended. One did not cover the other.

What is an individual with genotype AAA described as?
An Aa genotype can result in the same phenotype as either an AA or AA genotype, if one of the alleles acts in a dominant fashion. If the A allele is dominant over the a allele, then the phenotype of a heterozygous (Aa) individual will be the same as the phenotype of a homozygous dominant (AA) individual.
