In genetics, dominance pertains to the property of a gene (or allele) in relation to other genes or alleles. A gene or allele shows dominance when it suppresses the expression, or dominates the effects, of the recessive gene (or allele). There are many forms of dominance: complete dominance, incomplete dominance, and codominance. Codominance is a form of dominance wherein the alleles of a gene pair in a heterozygote are fully expressed.
To protect your skin from harmful UVA radiation, use a suntan lotion with a high sun protection factor. Lotions with plant-based oils, such as vitamin E-rich avocado oil, have enhanced effectiveness.

Hempseed oil, used either as a base or as a primary ingredient in many topical treatments, has many benefits.

Hemp oil is also high in gamma-linoleic acid, a substance that helps the skin with elasticity. In addition to their medicinal benefits, topicals help nourish and moisturize the skin.
