Terms in this set (79) Compare and contrast the terms codominance and incomplete dominance. When both alleles are equally expressed in the phenotype codominance is occurring.
When 2 alleles are equally expressed this is called?
If both alleles are dominant, it is called codominance?. The resulting characteristic is due to both alleles being expressed equally. An example of this is the blood group AB which is the result of codominance of the A and B dominant alleles.
When both alleles are the same it’s called?
If the two alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous.
When alleles are equally expressed in a heterozygote is called?
Closely related to incomplete dominance is codominance, in which both alleles are simultaneously expressed in the heterozygote. We can see an example of codominance in the MN blood groups of humans (less famous than the ABO blood groups, but still important!).
What are two alleles called?
Each pair of alleles represents the genotype of a specific gene. Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ.
Are both alleles expressed?
In most cases, both alleles are transcribed; this is known as bi-allelic expression (left). However, a minority of genes show monoallelic expression (right). In these cases, only one allele of a gene is expressed (right).
Is a recessive allele expressed?
If the alleles are different, the dominant allele will be expressed, while the effect of the other allele, called recessive, is masked. In the case of a recessive genetic disorder, an individual must inherit two copies of the mutated allele in order for the disease to be present.
When both the alleles dominant and recessive are equally expressed in the hybrid The phenomenon is known as?
