Clathrus ruber of the mature fruit bodies have been identified as carotenes, predominantly lycopene and "beta"-carotene—the same compounds responsible for the red and orange colors of tomatoes and carrots, respectively. Lycopene is also the main pigment in the closely related fungus "Clathrus archeri", while "beta"-carotene is the predominant pigment in the Phallaceae species "Mutinus caninus", "M. ravenelii", and "M. elegans". Clathrus ruber Clathrus ruber is a species of fungus in the stinkhorn family, and the type species of the genus "Clathrus". It is commonly known as the latticed stinkhorn, the basket stinkhorn, or the red cage, alluding to the striking fruit bodies
Labrador Retriever coat colour genetics characterized in mice and other mammals. Initial genetic studies of coat colour in dogs published in the 1950s concluded that there were two main genes involved, one distinguishing blacks from browns, and the other distinguishing blacks from reds and yellows. A 1977 study using crosses within a population of purebred Labradors showed the involvement of two specific genes in production of the three main coat colours of Labradors and described the underlying genetics of these colour varieties. The three recognised colours of Labrador Retrievers result from differences in two genetic loci that affect pigment expression. The first of these affects
