Describes the allele that is fully expressed when carried by only one of a pair of homologous chromosomes?
The allele that is fully expressed when carried by only one of a pair of homologous chromosomes is called a dominant allele. Dominant alleles mask the expression of recessive alleles when present in the genotype.
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.
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.
In some flowers there are two alleles for color and these can both be expressed equally at the same time Which best describes this trait?
This trait is known as co-dominance, where two alleles for a particular gene are both fully expressed in the phenotype. In this case, both colors are visibly present in the flower, rather than blending to create a new color.
What is it called when there are two different allies for a trait?
heterozygous (PS cant spell well but in essance that's the answer

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.
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.
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)
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.
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.
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.
In some flowers there are two alleles for color and these can both be expressed equally at the same time Which best describes this trait?
This trait is known as co-dominance, where two alleles for a particular gene are both fully expressed in the phenotype. In this case, both colors are visibly present in the flower, rather than blending to create a new color.

What is Co-dominant Alleles?
Co-dominant alleles are two different versions of a gene that are both fully expressed in a heterozygous individual. This means that both alleles contribute to the phenotype of the organism. An example of co-dominant alleles in humans is the ABO blood group system, where A and B alleles are co-dominant to each other.
How are homozygous and heterozygous allele combinations for a particular trait in plants different?
A homozygous trait is expressed when 2 of the same alleles make up the genotype. For example, if two alleles (A and a) were present, the homozygous trait would be either AA or aa. In general, a fully recessive trait is only expressed when it's homozygous.
