5 days ago · Definition. A carrier, as related to genetics, is an individual who “carries” and can pass on to its offspring a genomic variant (allele) associated with a disease (or trait) that is inherited in an autosomal recessive or sex-linked manner, and who does not show symptoms of that disease (or features of that trait).

Dec 20, 2023 · A carrier in genetics refers to an individual who carries a gene mutation for a particular genetic disorder without showing any signs or symptoms of the disease, but can pass the mutated gene on to their children.
May 28, 2023 · A genetic carrier pertains to an organism carrying an unexpressed defective gene for a recessive trait but when mated with another carrier can produce a homozygous offspring that expresses the recessive trait.
Carriers, by definition, are non-symptomatic individuals who carry a mutation in one of the two copies of a gene. This silent state is a reflection of the robustness of the human genome, which can tolerate such heterozygous conditions without significant impact on the individual’s health.
4 days ago · Carrier screening involves testing to see if a person “carries” a genetic variation (allele) associated with a specific disease or trait. A carrier has inherited a normal and a variant allele for a disease- or trait-associated gene, one from each parent.
Definition. In genetics and genomics, a carrier is generally used to describe an individual who has a genomic variant associated with a genetic condition, but does not have the condition themselves. Use in clinical context.
Genetic Carrier. The term ‘carrier’ or ‘carrier state’ refers to an individual who has different alleles for a given locus (conventionally considered ‘normal’ and ‘mutant’) on each member of a chromosome pair.
