Allele that is always expressed if present?
An allele that is always expressed when it is present is the dominant allele.
What is the difference between an inactive allele and an expressed allele?
The inactive allele is invisible in an organism while an expressed allele is the dominant allele and therefor is the phenotype.
Which form of gene pair is expressed when both dominant and recessive are present?
If the gene is governed by a dominant and recessive allele, then if the dominant allele is present, the dominant trait will be expressed. If both alleles are recessive, then the recessive trait will be expressed.
True or False In heterozygous individuals only the recessive allele is expressed?
In heterozygous individuals, only the dominant allele is expressed. The recessive allele is present, but not expressed
Why do we call some alleles dominant?
because it dominates the phenotype
When neither allele is dominant (they are both expressed)?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
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.
Allele that is always expressed if present?
An allele that is always expressed when it is present is the dominant allele.
What is an expressed allele in a heterozygote?
Dominant allele as opposed to recessive allele.
Does recessive allele is expressed if there is no dominant allele present?
YES
What is the difference between an inactive allele and an expressed allele?
The inactive allele is invisible in an organism while an expressed allele is the dominant allele and therefor is the phenotype.
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.
Allele that is fully expressed is referred to as?
No, it is referred to as dominant
Does a recessive allele need another recessive allele to be expressed?
I think if an allele "want" to be expressed, then it has to have a dominant allele. They don't need another recessive allele.
What is a dominent allele?
A dominant allele is an allele that can take over a recessive allele, so if you have a dominant allele and a recessive allele, then the offspring will most likely have a dominant allele over a recessive allele. The dominant allele is expressed over the recessive allele.
What is the term for an expressed allele?
dominant trait
Which form of gene pair is expressed when both dominant and recessive are present?
If the gene is governed by a dominant and recessive allele, then if the dominant allele is present, the dominant trait will be expressed. If both alleles are recessive, then the recessive trait will be expressed.
