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.

What is it called when the presence of two different alleles results in intermediate phenotype?
Incomplete Dominance
What type of inheritance that involves the partial expression of two different alleles is called .?
Incomplete dominance is the type of inheritance that involves the partial expression of two different alleles. This results in a blending of traits from both alleles, producing an intermediate phenotype.
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.
What does it mean if a trait demonstrates codominace?
Co-dominance occurs when two different alleles at a gene locus produce and intermediate result. In shorthorn cattle the combination of the white and red alleles produces roan. In poinsettia plants the combination of red and white alleles results in pink.
How do alleles interact in intermediate inheritance?
In intermediate inheritance, two different alleles at a single gene locus interact to produce a phenotype that is a blend of the two alleles. This results in a phenotype that falls between the dominant and recessive traits, rather than showing a clear dominant-recessive relationship. Both alleles contribute to the final phenotype in a co-dominant or blending manner.
A condition in which both alleles are dominant and cannot mask each other they blend?
This scenario is called incomplete dominance, where both alleles are expressed and blend together in the phenotype of an individual. This results in an intermediate or blended trait that is different from the traits produced by either homozygous genotype.
Is ABO blood group determined by multiple alleles?
Yes, the ABO blood group system is determined by multiple alleles. There are three main alleles involved in the ABO blood group system: A, B, and O. These alleles determine the presence or absence of specific antigens on red blood cells, which results in the different blood types (A, B, AB, or O).
Explain why a trait inherited by incomplete dominance such as the color of appoloosa horses is not a blend of two alleles?
Incomplete dominance occurs when the dominant and recessive alleles both contribute to the phenotype, resulting in an intermediate phenotype. In the case of Appaloosa horses, the spotted coat color is not a blended color but rather a distinct phenotype that is a result of both alleles influencing the expression of the trait. This is because each allele has a unique effect on the phenotype, leading to a different outcome than if the alleles were simply blended together.
What is called when the presence of two different alleles results in an intermidiate phenotype?
A)Polygenic Inheritance B) Multiple AllelesC)Incomplete Dominance D) Sex-Linked GenesThe answer is C = incomplete dominancePOSTED BYLexi Garcia Velasquez
What is the condition in which two different alleles are expressed equally when inherited?
Codominance is the condition in which two different alleles for a gene are both expressed and neither is dominant or recessive. This results in a phenotype that shows a mixture of the traits from both alleles.
What is a heterozygous mixture?
A heterozygous mixture refers to a situation where an individual has two different alleles of a gene at a specific locus. This results in a mixed genetic composition in the individual. This can impact the expression of traits and characteristics by combining the effects of the different alleles.
What type of allele dominance occurs when both alleles are active and expressed?
Either Co-dominance, where different parts of the organism display the different alleles (i.e. red and white flowers), or a combination of the two alleles (i.e. red and white alleles make pink flowers)
