What does being called a “carrier” for a specific trait mean?
Answers
Explanation:
A carrier is not affected by the disease it carries, thus the unfavorable allele is a recessive condition. This means an undesirable allele is present in the genotype of the carrier; but as the allele is recessive, there is no expression of disease symptoms, i.e. there is no development of the disease in the carrier. The carrier expresses the trait(s) controlled by corresponding dominant allele.
Hey dear,
➡️A hereditary carrier (or just carrier), is a person or other organism that has inherited a recessive allele for a genetic trait or mutation but usually does not display that trait or show symptoms of the disease. Carriers are, however, able to pass the allele onto their offspring, who may then express the genetic if they inherit the recessive allele from both parents. The chance of two carriers having a child with the disease is 25%. This phenomenon is a direct result of the recessive nature of many genes.
