The diagram shows the bone structure of the front legs of two animals: a frog (amphibian) and an alligator (reptile). shading is used to identify similar bones.

how does a comparison of the bone structures of the two animals provide evidence of an evolutionary relationship?

a.
the analogous structures are evidence that one animal evolved from the other.

b.
the homologous structures are evidence of descent with modification from a common ancestor.

c.
the homologous structures are evidence that one animal evolved from the other.

d.
the analogous structures are evidence that the two animals do not share a recent common ancestor.

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.
