What term describes a gene with two dominant alleles that are expressed at the same time?
Co-dominance.
At is a gene with two dominant alleles that are expressed at the same time?
Co-dominant or incomplete dominance situation.
Is it true that recessive alleles are never present when dominant alleles are present?
No. They are present but not expressed (seen). Only the dominant alleles are expressed.
What is an interaction between alleles in which both alleles are expressed more or less equally or a blending occurs called?
Those would be called co-dominant alleles.
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.
In what alleles can be observed in the phenotype?
you mean phenotype, and its dominant alleles
Why you called co-dominance when a person possess two different alleles at the same locus and both alleles are expressed in the phenotype?
Both of the parent's alleles are either dominant or recessive.
What are the circumstances under which dominant alleles will be expressed?
A dominant allele will be expressed when an allele pair is homozygous or heterozygous dominant.
When two different alleles occur together the one that is expressed is called?
Dominant.
The gene that is fully expressed when two different alleles are present is the?
Dominant alleles :) hope i helped
A dominant genetic disorder will be expressed if an individual has?
Two dominant alleles that cause the disorder.
What is the name of inheritance pattern in which both alleles are expressed equally?
It depends on what you mean by "both are expressed". In order for both alleles to be expressed, both alleles must be dominant alleles. If one allele is recessive, it will be masked. If you are talking about alleles that are co-dominant, then both alleles would be expressed together. Ex: Red x white = red and white flower If you are talking about incomplete dominance, then both alleles are seen as a blend of both in the offspring. Ex: red x white = pink flower If you are talking about multiple alleles (like in human blood typing), then you can see 2 alleles expressed together. Ex: Type A x Type B can produce AB blood type.
