When the alleles of a gene pair are expressed differently but neither is dominant to the other?
Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed.

What is a condition in which both alleles for a gene are fully expressed?
both the alleles are expressed when the alleles are co-dominent, which means neither is dominant or recessive and cannot be masked. SOme examples are blood type. Type AB blood type is one co-dominent allele for a (Ia) and one for b (Ib).
Genetic trait that is expressed when it's allele is homozygous or heterozygous?
The complete expression of both alleles (i.e. for example, a black and white cow), is known as co-dominance, when each allele is equally dominant over the other. However, both alleles may be expressed in the form of an intermediate as well (i.e. white and red alleles forming a pink intermediate for flower petals), known as incomplete dominance, when neither allele is completely dominant over the other.
Some alleles are neither dominant or recessive and many traits are controlled by what?
Each person has two alleles of one particular gene, which controls one particular characteristic, such as a person's blood group. An allele may be either dominant, recessive, or codominant. A dominant allele would dominate the other allele in the chromosomes, meaning only the dominant allele would contribute to an organism's characteristics. An example of this is the A blood group, which is dominant to the O allele. However, if an individual has both A and B alleles, A and B are codominant, as they both exhibit effects on an organism's characteristics (the blood group). This results in an AB blood group - a combination of the effects of two genes!
How would you write an allele that is heterozygous?
Representing heterozygote allele characteristics depends on the nature of the heterozygote.If one of the alleles is dominant, and the other recessive, the genotype is written as Aa - where the capital letter (A) represents the dominant allele, and the lower case letter (a) represents the recessive allele. The dominant (upper case) allele is always written first.However, the genotype cannot be written in this way if both alleles are codominant (neither one is dominant or recessive). In this case, the convention is to choose a letter to refer to the flower-color-locus as a whole. You would then add different superscript letters to denote the different alleles.For example, you could choose the letter A to refer to the flower-color-locus, and then choose C and D as the two co-dominant alleles. This genotype would be written as ACAD.
Is unibrow dominant or recessive?
its neither. its a learned skill. i can do it, and i learned to by holding one eyebrow up, with my finger, and learning to adapt from that. you use muscle in your face when you do it. if you want to learn, wrinkle your forehead that will help you.
When neither allele is dominant what are they expressed as?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
When neither allele is dominant (they are both expressed)?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
What is it when an allele is neither dominant nor recessive?
When an allele is neither dominant nor recessive, it means that both alleles equally influence the trait. This is known as codominance, where both alleles are expressed in the phenotype of the individual.
When are both alleles expressed in offspring?
Both alleles are expressed in offspring when neither allele is dominant over the other, resulting in co-dominance. This means that both alleles are simultaneously expressed in the offspring's phenotype.
What Happens when genes are neither recessive nor dominant?
When genes are neither recessive nor dominant, they are said to exhibit incomplete dominance or co-dominance. In incomplete dominance, both alleles are expressed in the phenotype, resulting in a blending of traits. In co-dominance, both alleles are fully expressed in the phenotype, leading to a combination of traits.
How is it possible to have neither allele dominant?
In cases where neither allele is dominant, both alleles are expressed equally in the phenotype. This is known as codominance, where both alleles contribute to the phenotype without one overpowering the other. An example of this is in blood type inheritance, where the AB blood type is the result of codominance between the A and B alleles.
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).
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.
Alleles are neither dominant nor recessive?
codominance
If the alleles are neither dominant or recessive what happens?
If neither are Dominant Or Recessive then its called co dominance or spuedo - dominance
When neither gene in a genotype pair is dominant and neither gene is recessive the genes are said to be .?
Incomplete dominant alleles.
What is a condition in which neither of two alleles of a gene is dominant or recessive?
Codominance is a condition in which neither of two alleles of a gene is dominant or recessive. In codominance, both alleles are expressed in the phenotype of the heterozygote, resulting in a unique phenotype that is a mixture of the two alleles.
