Definitions:

Recessive Allele

A variant of a gene that must be inherited from both parents to be expressed in the offspring, in contrast to a dominant allele.

Carriers

Individuals who possess one copy of a mutated gene for a recessive genetic condition but do not exhibit symptoms of the condition themselves, though they can pass the gene to offspring.

Dominant Gene

A gene that is expressed in the phenotype even when only one copy is present in the genotype.

Genetic Characteristics

Traits and features that are determined by genes inherited from one's parents, affecting physical and sometimes behavioral aspects.
