Genotype refers to the specific genetic makeup of an organism, including all the alleles it possesses for various traits. It is not considered "incomplete" in itself; rather, it provides a complete representation of an organism's genetic potential. However, the expression of that genotype can be influenced by environmental factors, leading to variations in phenotype, which may sometimes make it seem incomplete in terms of observable traits.

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.
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!
Experiments with four o'clock flowers produced examples of what kind of dominance?
Experiments with four o'clock flowers typically exhibit incomplete dominance, where the heterozygous genotype results in an intermediate phenotype between the two homozygous genotypes.

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.
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.
When the heterozygous genotype results in a phenotype where both alleles are fully and separated expressed?
codominance.

What is 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.
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
Which is an example of imcomplete dominance?
An example of incomplete dominance is when crossing a red flower with a white flower produces pink flowers in the offspring, rather than a blend of the two parent colors. This occurs when the heterozygous genotype results in an intermediate phenotype that is different from either homozygous genotype.
What type of inheritance when the genotype is neither homozygous or heterozygous?
When the genotype is neither homozygous nor heterozygous, it typically indicates incomplete dominance or codominance. In incomplete dominance, the two different alleles are neither dominant nor recessive, resulting in a blending of phenotypes. In codominance, both alleles are expressed fully in the phenotype, leading to distinct traits from each allele being visible.
