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).
This is codominance, and in humans it can be seen in blood types. Type A and type B genes are codominant, so both are expressed if present, and the person is type AB. Type O is recessive to both A and B genes.
When both alleles for a gene are expressed in an individual, this is codominance.
Tanong mo sa pagong! ;) joke di ko ito masasagot eh sorry po. :)
This is called Codominance because both genes are expressed

Codominance
Heredity
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.
Recessive. Dominant alleles are expressed in both homozygous and heterozygous individuals (DD or Dd), but recessive alleles are only expressed in homozygous individuals (dd).
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.
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.
You are supposed to have 2 alleles in a single nucleus and if not there can be a disorder i believe.
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.
codominance.
When both the alleles are expressed, it is called co-dominance or mixed dominance.
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).
Both of the alleles must be recessive. The trait expressed is a recessive trait.
both alleles are expressed in the offsping
This is called Codominance because both genes are expressed in an offspring.
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.
If it's not a heterozygous, the alleles would either be two capital letters (TT) or two lowercase letters (tt). This is because the organism has either both two dominant alleles or two recessive alleles.
Both of the parent's alleles are either dominant or recessive.
Co-dominance.
Both of the alleles must be recessive. The trait expressed is a recessive trait.
