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.

What are inactive alleles?
Inactive alleles (usually called recessive) are not fully expressed in the phenotype of the organism.
The gene that is fully expressed when two different alleles are present is the?
Dominant alleles :) hope i helped
When one trait is not completely dominant over another?
This is called codominance in this case, neither allele is dominant over another, it creates in heterozyogous individuals a phenotype that is not in intermediate, nor the phenotype either of the two alleles create, but rather, a different phenotype.
When there are two different alleles for a trait?
If you have a heterozygous genotype (X, x), then you would take on the phenotype of the dominant allele. There are some instances where neither trait is fully dominant over the other. This is called incomplete dominance, and usually results in a blending effect of the two traits.
What is the difference between polygenic inheritance and incomplete dominance?
Codominance and incomplete dominance are the same in that they both apply to a heterozygote (an organism with two different alleles for one trait).The difference is in how the two different alleles are expressed in the phenotype, or appearance, of the organism.In codominance, you can see the effect of both alleles distinctly. A person who has one allele for type A blood and one allele for type B blood will have type AB blood. You can see the effects of both the A and the B allele, but they remain distinct from each other.In incomplete dominance, the effect of the two alleles is more blended, as if neither allele can completely overpower the other. In some flowers, plants with two alleles for white color are white, and plants with two alleles for red color are red, but a heterozygote with one allele for red and one for white is pink. (Not red and white as you'd see with codominance.)

Using the terms dominant recessive explain the difference between genotype and phenotype?
No, I think you have your terms confused.The terms "dominant" and "recessive" are applied to alleles of a genotype. A genotype is an expression (using upper- and lower-case letters) that shows what alleles an organism has for a particular locus. The two alleles (in most cases) inherited (one from mother and one from father) can either be dominant or recessive. The recessive allele is not fully expressed in the presence of the dominant allele and is only expressed when there are two recessive alleles. The genotype could be called "recessive" I suppose if the genotype is homozygous recessive. But remember that two recessive alleles as a genotype is only one possibility - in which case you can't say the "genotype is recessive".The phenotype is dependent on the genotype. If present, the dominant alleles (in simple Mendelian genetics) will determine the phenotype - what the organism's trait or characteristic is. The phenotype will never be what is coded by the recessive allele unless the genotype is two recessive alleles.
When the heterozygous genotype results in a phenotype where both alleles are fully and separated expressed?
codominance.
Which statement is TRUE about multiple alleles?
MULTIPLE CHOICES a. It happens when two or more alleles control the inheritance of a character. b. It refers to traits that are controlled by genes located on the same-sex chromosomes. c. It occurs when two dominant alleles of a contrasting pair are fully expressed at the same time in a heterozygous individual. d. It occurs when the phenotype of the offspring is somewhere in between the phenotype of both parents.
Is this true or false in codominance the alleles are neither dominant nor recessive?
True - in codominance neither allele is dominant or recessive. Codominance results in both alleles being expressed in the phenotype (characteristics of the organism). For example, if R is red and W is white - a flower with the genotype RW would have white petals with red patches (or something similar).
Which occurrence is when an individual inherits a dominant gene but does not fully express the dominant phenotype?
Incomplete penetrance
When one trait is not completely dominant over another?
This is called codominance in this case, neither allele is dominant over another, it creates in heterozyogous individuals a phenotype that is not in intermediate, nor the phenotype either of the two alleles create, but rather, a different phenotype.
When two alleles for a trait are different?
If you have a heterozygous genotype (X, x), then you would take on the phenotype of the dominant allele. There are some instances where neither trait is fully dominant over the other. This is called incomplete dominance, and usually results in a blending effect of the two traits.
Allele that is fully expressed is referred to as?
No, it is referred to as dominant
What does co-dominant means?
Co-dominance happens when two genotypes are expressed at the same time. For example, one parent can have blood type A and one parent can have blood type B and together produce a child with blood type AB. If two parents have the blood type AB, the child has a chance of being mentally ill.
When there are two different alleles for a trait?
If you have a heterozygous genotype (X, x), then you would take on the phenotype of the dominant allele. There are some instances where neither trait is fully dominant over the other. This is called incomplete dominance, and usually results in a blending effect of the two traits.
