Fungi of the phylum basidiomycota form mycorrhizal associations with orchids, a type of flowering plant. how do these associations benefit both the fungi and the orchids a. the orchids gain nutrients and carbon dioxide from the fungi, while the fungi gain oxygen and sugar from the orchids. b. the orchids release enzymes to break down sugar for the fungi, while the fungi fertilizes the soil surrounding the plant. c. the orchids receive water and oxygen from the fungi, while the fungi receive food and minerals from the orchids. d. the orchids produce decaying material for the fungi, while the fungi provide structural support to the orchids.

In a hypothetical breed of dogs, coat color is controlled by two genes. there are six different coat colors in this breed: black, brown, cream, gray, silver, and tan. consider the following crosses. cross 1: black females from a lineage of all black dogs are crossed with brown males from a lineage of all brown dogs. f1 males and females are all black. when f1 are intercrossed, f2 males and females are black or brown. cross 2: black females from a lineage of all black dogs are crossed with tan males from a lineage where all males are tan and all females are cream. f1 males are black, f1 females are gray. when f1 are intercrossed, f2 males and females are black, brown, gray, or tan. cross 3: silver females from a lineage where all females are silver and all males are gray are crossed with brown males from a lineage of all brown dogs. f1 males and females are all gray. when f1 are intercrossed, f2 males are black, brown, gray, or tan, f2 females are cream, gray, silver, or tan. select the correct statements regarding the mode of inheritance of the coat color genes. a) both genes are x-linked. b) both genes are autosomal. c) one of the genes modifies the expression of the other gene. d) each gene has an additive effect on the intensity of coat color. e) each gene independently specifies three colors. f) one of the genes is autosomal, and the other is x-linked.
