In genetics, dominance is the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome. The first variant is termed dominant and the second recessive.

What does dominance mean in a relationship?

"Dominance means that your partner is attempting to limit your power," Roberts says. "It's not a sign of someone who cares about you. It means they care about them and are attempting to control your decision making or manipulate you. It's unhealthy and emotionally abusive."

What are examples of dominance?

A classic example of dominance is the inheritance of seed shape (pea shape) in peas. Peas may be round (associated with allele R) or wrinkled (associated with allele r). In this case, three combinations of alleles (genotypes) are possible: RR and rr are homozygous and Rr is heterozygous.
