The term "hidden gene" often refers to "silent mutations" or genes that are not expressed under normal conditions but can be activated under specific circumstances. In some contexts, it may also refer to "epigenetic" changes that silence or activate certain genes without altering the DNA sequence itself. Another interpretation could be "cryptic genes," which are present in the genome but not typically expressed or identified in standard analyses.
The dominant gene will always "cover up" the recessive gene, although there are instances of codominance, in which both phenotypes will be displayed, because one gene is not completely dominant over the other. There is also what is called 'incomplete dominance', when the actual phenotype is somewhere between the two.
Recessive
In a heterozygote, there are two different alleles for a specific gene. One allele is dominant and will be expressed, while the other allele, called the recessive allele, is not expressed but is still present in the genetic makeup of the individual. The recessive allele is "hidden" in the heterozygote because its presence does not affect the outward appearance or expression of the dominant allele.
It is called gene replication or gene duplication.
A hypothetical gene is a predicted gene sequence that has not been experimentally characterized or validated. It is based on computational predictions and analysis of genomic data, and its functions and existence may require further experimental verification.
A person with a hidden gene for a particular disease is commonly called a carrier. This person carries a gene for a disease, however, the disease may not always attack the person's body.
A gene that shows no impact on a trait in a heterozygous state is called a recessive gene. In a heterozygous individual, the dominant gene will determine the trait expressed, while the recessive gene remains hidden.
The hidden or masked form of a gene is called recessive. Recessive genes are only expressed when an individual carries two copies of the recessive allele. When a dominant allele is present, it will be expressed instead of the recessive allele.
The dominant gene will always "cover up" the recessive gene, although there are instances of codominance, in which both phenotypes will be displayed, because one gene is not completely dominant over the other. There is also what is called 'incomplete dominance', when the actual phenotype is somewhere between the two.
Recessive
Recessive
A recessive gene is a gene whose effect can be hidden in the presence of a dominant allele. This means that an individual needs to inherit two copies of the recessive allele in order for its effects to be observed.
The expression of a gene is called the phenotype.
It is called gene replication or gene duplication.
In a heterozygote, there are two different alleles for a specific gene. One allele is dominant and will be expressed, while the other allele, called the recessive allele, is not expressed but is still present in the genetic makeup of the individual. The recessive allele is "hidden" in the heterozygote because its presence does not affect the outward appearance or expression of the dominant allele.
gene flow
A gene that can be masked by another gene is referred to as a recessive gene. This means that the trait associated with the recessive gene is expressed only when two copies of the gene are present.
