Verified step by step guidance

Understand the definition of genetic variants: Genetic variants are differences in the DNA sequence among individuals. These can occur anywhere in the genome, including both coding and non-coding regions.

Evaluate the inheritance patterns of genetic variants: Variants are not always inherited in a dominant manner; they can be dominant, recessive, co-dominant, or show other complex inheritance patterns.

Consider the location of variants: Variants can occur in coding regions (which directly affect protein sequences) as well as in non-coding regions (which can regulate gene expression).

Assess the phenotypic impact of variants: Not all genetic variants lead to observable phenotypic changes; some may be neutral or have effects only under certain environmental conditions.

Recognize gene-gene interactions (epistasis): Genetic variants can influence the expression of other genes through interactions, affecting phenotypes in complex ways beyond simple inheritance patterns.
