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. Vitamin E helps prevent premature skin aging due to sun exposure. Remember, there is no such thing as a safe tan.
Perhaps the most important aspect of sunflower oil is its high vitamin E content. The health benefits of consuming vitamin E, or using it on the skin, have been studied for years and can be beneficial to your body in a variety of ways.
