Labrador Retriever coat colour genetics fur colour but those with black skin can potentially produce a Dudley. Dudleys breed true for both fur and skin. The ability of the E locus to override the coat colour directed by the B locus is a classical example of epistasis, where multiple genetic loci affect the same observed trait. The E locus also determines whether the phenotype due to the third genetic locus affecting coat colour will be evident. This locus is recognised as affecting coat colour through the expression of pheomelanin, the pigment responsible for red and yellow pigmentation. The effects on pheomelanin pigmentation are only seen
Lycopene food, or as a dietary supplement, and any of these cancers." A 2017 review concluded that tomato products and lycopene supplementation had small positive effects on cardiovascular risk factors, such as elevated blood lipids and blood pressure. A 2010 review concluded that research has been insufficient to establish whether lycopene consumption affects human health. Lycopene has been studied in basic and clinical research for its potential effects on cardiovascular diseases and prostate cancer, although results through 2017 have not changed the prevailing FDA view that evidence of benefit remains inconclusive. Lycopene Lycopene (from the neo-Latin "Lycopersicum", the tomato species) is
