Answer:

What Is the Evidence for Evolution? Darwin used multiple lines of evidence to support his theory of evolution by natural selection -- fossil evidence, biogeographical evidence, and anatomical evidence. Comparative embryology is the study of the similarities and differences in the embryos of different species. Similarities in embryos are likely to be evidence of common ancestry. All vertebrate embryos, for example, have gill slits and tails. ... In humans, the tail is reduced to the tail bone.

Image result for Three lines of evidence that provide support for common ancestry and evolution are Similar embryology, Molecular homologies, and The Fossil Record.

Molecular similarities provide evidence for the shared ancestry of life. DNA sequence comparisons can show how different species are related. Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved.

aleksklad [387]

Answer:

9/16 A_B_ White colour, axial flower

3/16 A_bb White colour, terminal flower

3/16 aaB_ Yellow colour, axial flower

1/16 aabb Yellow colour, terminal flower

Explanation:

Let the flower colour allele be represented by A and the flower position by B. The dominant white colour would be A while the alternate version (the yellow colour) would be a. Also, the dominant axial flower position would be B while the alternate terminal position would be b.
