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.

How does codominance change the offsprings phenotype?
Codominance is contrary to typical mendelian genetics, in that no one allele is dominant to the other, so they are both expressed equally. The important part is that the offspring with express each allele independently, such as having spots of one color, then spots of another color, instead of blending the two colors, which would be incomplete dominance. So codominance changes the offsprings phenotype by making the offspring express both alleles equally, yet each allele's expression is separate/distinguishable, not blended.
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.
In what both alleles are expressed in offspring?
Incomplete Dominance
What is meant by mono-hybrid inheritance including co dominance?
Monohybrid inheritance refers to the inheritance pattern of a single trait controlled by one gene with two alleles, where one allele may be dominant over the other. In this context, co-dominance occurs when both alleles are expressed equally in the phenotype of the heterozygote, resulting in a distinct phenotype that showcases both traits. An example of co-dominance is seen in blood types, where individuals with one allele for type A and one for type B express both A and B antigens on their red blood cells, resulting in type AB blood. This illustrates how different alleles can interact to produce a unique expression of traits in offspring.
When both alleles are expressed in offspring is what?
Codominance is when both alleles are expressed in the offspring. This results in a phenotype where traits from both alleles are visibly present. An example of codominance is the ABO blood group system in humans.

How is the inheritance of traits controlled in organisms?
Inheritance of traits in organisms is controlled by genes, which are segments of DNA that code for specific traits. These genes are passed from parents to offspring through sexual reproduction. The combination of genes from both parents determines the traits that are expressed in the offspring.

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.

What process can best be explained by alleles?
The process of inheritance is best explained by alleles, which are different versions of a gene that determine specific traits. During reproduction, alleles from both parents combine, resulting in offspring with a unique set of alleles that influence their characteristics. This genetic variation is fundamental to evolution and natural selection, as it allows for diverse traits within a population. Additionally, the interaction of dominant and recessive alleles can determine how traits are expressed in the offspring.
How inheritance by multiple alleles and polygenic inheritance are similar?
I think that , they r both controlled by more then 2 allels.
What is it called when both alleles are expressed in an offspring?
This is called Codominance because both genes are expressed in an offspring.
How inheritance by multiple alleles and polygenic inheritence are similar?
In both cases, traits are influenced by multiple genetic factors. Inheritance by multiple alleles involves the presence of more than two alleles for a particular gene, while polygenic inheritance involves the contribution of multiple genes to a single trait. Both types of inheritance result in continuous variation, with traits being influenced by the interaction of multiple genetic factors.
What is it when two alleles are both equally dominant and will both show up?
codominance
