not usually, most books fit into the normal genres: mystery, fiction, nonfiction, adventure etc.
I believe this person is referring to "genes," not "genres." To answer the question, then: yes, you can have genes that are not expressed. Recessive genes, for example, will not be expressed in heterozygous individuals; they will only be expressed in homozygous recessive individuals. For example; if you have the genotype Aa, the recessive gene - "a" - will not be expressed because the genotype contains a dominant allele, and the dominant allele will always be the one expressed. The only way that the "a" allele will be expressed is, again, if you are homozygous for that recessive gene (your genotype would be aa).
A recessive trait .and just in case you need it,a gene that is expressed in an organism is a dominant trait
Yes. These are called recessive genes
This is the dominate gene, and is normally represent by a capital letter. Then gene which is not expressed is the recessive gene and is represented by a lower case letter. For example the if someone had expressed a brown eyed phenotype and did not carry the gene for blue eyes it be represented as BB (B standing for Brown). If they expressed the brown eye phenotype and also carried the gene for blue eyes it would be represented as Bb (b does not stand for blue it stands for NOT BROWN) While if someone had blue eyes it would be represented as bb
A dominant gene refers to a gene that is expressed over another gene in the same position on a chromosome. It will always show its trait in the individual's phenotype if it is present in their genotype. For example, if a person inherits a dominant gene for brown eyes, they will have brown eyes regardless of whether they also have a recessive gene for blue eyes. On the other hand, a recessive gene refers to a gene that is not expressed when there is a dominant gene present. It is only expressed in the phenotype when there are two copies of the recessive gene in the genotype. An example is the gene for blue eyes, which will only be expressed when an individual has two copies of the recessive gene and no dominant gene for brown eyes.
Coding sequences of a gene are expressed as protein
One gene on a chromosome is expressed, while the other gene on the homologous chromosome, being recessive, is not expressed.
Alleles are alternate versions of genes that code for certain phenotypes, or traits. The traits of an individual are a result of the interaction between their genotype (alleles) and the environment.
Heterozygous.
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.
No. If a gene is expressed, it is turned on.

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.
Genotype is the alleles (different forms of a gene) which an individual has with respect to a particular characteristic. The Phenotype is how these genes are expressed in an individual.
Two dominant alleles that cause the disorder.
One gene on a chromosome is expressed, while the other gene on the homologous chromosome, being recessive, is not expressed.
