a cell produces only the proteins it needs.
No. If a gene is expressed, it is turned on.
Coding sequences of a gene are expressed as protein
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.
How is a gene not expressed
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.
A recessive gene.
the dominant gene

When we say that a gene is expressed, it means that the information encoded in the gene is used by the cell to make a specific protein or functional RNA molecule. This process is known as gene expression.
Yes, if a trait is controlled by a dominant gene, it will be expressed regardless of the instructions of the corresponding gene in the other half of the pair. Dominant genes only require one copy to be expressed in the phenotype.
A recessive gene is a gene that is only expressed if an individual has two copies of it, one inherited from each parent. In the presence of another dominant gene, the recessive gene's trait is not expressed.
