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).

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 the type of allele that only effect the phenotype in the homozygous chromosome?

Recessive. Dominant alleles are expressed in both homozygous and heterozygous individuals (DD or Dd), but recessive alleles are only expressed in homozygous individuals (dd).


What is the difference between dominant and recessive alleles for specific traits?

Dominant is an allele that will always be expressed in a heterozygous individual. Recessive on other hand are traits that will only be expressed in a homozygous condition. Organisms receive one allele for each trait from each parent, thus you have two alleles for each trait.


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.


When both dominant and recessive alleles are present within a single nucleus the organism is for the trait?

You are supposed to have 2 alleles in a single nucleus and if not there can be a disorder i believe.

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.


What is co-dominant disorder?

A co-dominant disorder is a genetic condition where both alleles of a gene are fully expressed, resulting in a phenotype that reflects a combination of both alleles. This can lead to a distinct phenotype that is different from both homozygous states.


The gene that is fully expressed when two different alleles are present is the?

heterozygous gene. In this situation, both alleles are different and both are expressed, resulting in a blending or mixing of their traits.


If two dominant alleles are expressed at the same time this is a case of what?

This is called codominance. In codominance, both alleles are fully expressed in the phenotype of the individual.


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 the condition in which there's more than one dominant allele?

Codominance is when an organism has two different dominant alleles, so both of them are expressed.When an organism has two identical dominant alleles, it is homozygous.


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 many alleles are there in codominance?

In codominance, there are at least two alleles contributing to the phenotype of an individual, each allele independently expressed. This means that both alleles are fully expressed in the heterozygous genotype, resulting in a distinct phenotype.


At is a gene with two dominant alleles that are expressed at the same time?

In genetics, gene with two dominant alleles that are expressed at the same time is known as codominance. This results in a phenotype where both alleles are equally and fully expressed in the offspring. An example of codominance is the AB blood type in humans, where the A and B alleles are both expressed on the surfaces of red blood cells.


What is a type of inheritance where both alleles show equally in The Offspring?

The type of inheritance where both alleles are expressed equally in the offspring is known as codominance. In codominance, neither allele is dominant or recessive, resulting in a phenotype that displays characteristics of both alleles simultaneously. A classic example of this is seen in certain blood types, such as AB blood type, where both A and B alleles are fully expressed.


A pattern in which both versions of a gene show?

A pattern where both versions, or alleles, of a gene are fully expressed in the phenotype is called codominance. In this scenario, the traits associated with both alleles are visible in the offspring. An example is the ABO blood group system, where an individual can have both A and B antigens expressed on their red blood cells if they inherit both A and B alleles.


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

codominance.
