Genetic carrier
Genetic Carrier
A Genetic Carrier (pronunciation: /dʒɪˈnɛtɪk ˈkærɪər/) is an individual who has inherited a recessive gene for a genetic disorder but does not display that disorder's symptoms.
Etymology
The term "Genetic Carrier" is derived from the field of genetics, which studies heredity and the variation of inherited characteristics. The word "carrier" refers to the individual's ability to carry and potentially pass on the genetic disorder to their offspring.
Related Terms
- Genetic Disorder: A disease caused by abnormalities in an individual's genome.
- Recessive Gene: A gene that gets masked by a dominant gene.
- Dominant Gene: A gene that expresses itself over a recessive gene.
- Genome: The complete set of genes or genetic material present in a cell or organism.
- Heredity: The passing on of physical or mental characteristics genetically from one generation to another.
Definition
A Genetic Carrier is a person who has inherited a recessive allele for a genetic trait or mutation but does not display that trait or outwardly show symptoms of the disease. Carriers are, however, able to pass the allele onto their offspring, who may then express the gene if they inherit another recessive allele from the other parent.
Importance
Understanding the concept of a Genetic Carrier is crucial in the field of genetic counseling. It helps in predicting the likelihood of a couple having a child with a genetic disorder. Genetic carriers can be identified through genetic testing, which can be important for individuals with a family history of a particular disease.
