Definitions:

Symbolic

Pertains to symbols or the use of symbols to represent ideas or qualities.

Recessive Alleles

Alleles that produce their characteristic phenotype only when two copies are present, as opposed to dominant alleles which can express with only one copy.

Phenotype

describes the observable characteristics or traits of an organism, resulting from the interaction of its genetic composition with the environment.

Heterozygous Carriers

Individuals who have one copy of a recessive gene and one normal gene for a particular trait, potentially passing the recessive gene to their offspring.
