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)

What type of allele dominance occurs when both the alleles are active and expressed?
When both the alleles are expressed, it is called co-dominance or mixed dominance.
When one allele shows dominance over another allele?
When one allele shows dominance over another it is masking the expression of the other allele which is called "recessive".The word for this is complete dominance.
What is expressed when neither copy of an allele completely masks expression of the other but instead a bending of alleles is seen?
incomplete dominance
When one allele does not mask the other and both show AB blood type?
This is an example of co-dominance in which both alleles are expressed equally.
What is the term for dominance in which the dominant allele is always expressed?
Complete dominance

What is expressed when niether copy of allele completely masks expression of the other but instead a blending of alleles is seen?
dominance :) i think its dominance.
What is shared dominance?
Shared dominance, or co-dominance is when a single gene has more than one dominant allele. In shared dominance both alleles are expressed completely.
How does incomplete dominance function at the molecular level?
One funcional allele is insufficient to produce the dominant pheontype. Both alleles are expressed as an intermediate of the alleles.
What is expressed when neither copy of an allele completely masks expression of the other but instead a bending of alleles is seen?
incomplete dominance
If both alleles are equally expressed in a heterozygote the relationship is called?
The expression of more than one allele is referred to as incomplete dominance. For example a flower that is heterozygous red and white will have a pink phenotype.
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.
According to the rule of dominance if two different alleles are present is the dominant allele expressed?
the dominant allele is expressed when two (assuming you mean dominant and recessive) alleles are present. however, if the alleles are codominant they are both expressed.
When one allele does not mask the other and both show AB blood type?
This is an example of co-dominance in which both alleles are expressed equally.
What Dominant alleles are both fully expressed in a phenotype?
The form of inheritance in which two (different) alleles are both expressed is called codominance. An example of codominance is the orange and black coat of a type of calico cat called a tortoiseshell. Both the orange allele and the black allele for coat color are expressed.
Two dominant alleles are expressed at the same time?
The alleles are not always both expressed.Take the simplest example, a case when there are only two alleles for a trait, R and r. When the organism is a heterozygote, meaning that it has both alleles with a genotype of Rr, only the phenotype carried by the dominant allele, the R, will be expressed. The dominant allele masks the phenotype of the recessive allele. A case in which only the dominant phenotype is expressed in a heterozygote is a case of complete dominance.*Cases where the dominant allele does not completely mask the recessive allele are cases of incomplete dominance and co-dominance.In incomplete dominance, the dominant allele has some effect on the recessive allele, but not a full effect. This results in a third phenotype in the population. Think red and white flowers leading to pink flowers.In co-dominance, the dominant allele has as much effect on the phenotype of the organism as the recessive allele. Think red and white flowers now leading to red and white streaked flowers.
