Suppose in a species of petunia, both locus a and locus b can independently determine petal color. at locus a, pink (a) is dominant over white (a). at locus b, pink (b) is also dominant over white (b). if there are dominant alleles at both loci, magenta petals are produced. if an aa bb plant is crossed to an aa bb plant, what is the ratio of magenta‑ to pink‑ to white‑flowered petunias expected in the f2 progeny?

What is true of all organisms in the kingdoms protista, plantae, fungi, and animalia? a. they are multi-celled. b. they are photosynthetic. c. they have cells that contain membrane-bound organelles. d. they contain cells that lack membrane-bound organelles.

The embryos of a bird, a reptile, and a mammal are similar in appearance. how does comparing the physical appearance of embryos of different species support the theory of evolution? a. it shows that these organisms share a common ancestor. b. it provides evidence that these organisms eat the same foods. c. it shows that these organisms share the same habitat. d. it provides evidence that these organisms suffered a genetic mutation.
