a gene being expressed means it is shown, for example if you have the gene for brown eyes and the gene for blue eyes, only one can be expressed. if you have brown eyes that gene is expressed, if not the blue-eye gene is expressed.

What is a trait that is expressed even if only one gene for that form of the trait is inherited?
It is a dominant trait. You only need one gene of a dominant trait for that trait to be expressed. You need two copies of the recessive trait in order for the trait to be expressed.
What does it mean for a gene to be turned off or not expressed?
Transcription into RNA does not occur for that gene.
Will a A trait controlled by a dominant gene be expressed even if the instructions of the corresponding gene in the other half of the pair are different?
Yes, a trait controlled by a dominant gene will be expressed even if the instructions of the corresponding gene in the other half of the pair are different.
What is a reccesive gene?
an allele that is not expressed when paired with a dominant allele. Only expressed when paired with another recessive allele.
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.
What is is the principal of dominance?
One gene on a chromosome is expressed, while the other gene on the homologous chromosome, being recessive, is not expressed.
Is an expressed gene turned off?
No. If a gene is expressed, it is turned on.
Which parts of a gene are expressed as protein?
Coding sequences of a gene are expressed as protein
What does it mean for a gene to be off?
How is a gene not expressed
Individual that has one copy of a expressed gene has a genotype known as?
Heterozygous.
What is a trait that is expressed even if only one gene for that form of the trait is inherited?
It is a dominant trait. You only need one gene of a dominant trait for that trait to be expressed. You need two copies of the recessive trait in order for the trait to be expressed.
What gene that is always expressed and will produce a trait?
The gene that is always expressed and will produces a trait is a genetic statistic. This statistic is what is created when the gene is dominant.
What is the gene that is not expressed due to the influence of a dominant gene called?
Purebred
What is the physical trait that gets expressed by a gene pair?
the dominant gene
What would be the advantages of inserting into a plasmid gene with a highly visible phenotype?
Inserting a plasmid gene into the organism gives us three situation that one is the foreign cell may not pick up the plasmid the second chance is it is picked up may not expressed and in the third case it is expressed and therefore you can have the gene of interest. This is the one main advantage of studying the gene of interest by inserting a plasmid gene.
A genetic trait expressed in a person who has only one copy of the gene associated with the trait?
Dominant
What does it mean for a gene to be turned off or not expressed?
Transcription into RNA does not occur for that gene.
