Question

HELP

Answer 1

The genomes of three species of mouse are being sequenced, and a particular DNA sequence found in all three species is found to have a steady mutation rate. The sequence of interest for these three species is shown below.

Species A: ATTCGGATTATTCGAGG
Species B: GTCCGGTTCATTGGACA
Species C: ATCCAGATCGTTCGTGG

Which of the following inferences can be made, based on this information?
Answer
Species A and Species C most likely share the most recent common ancestor since they differ by the fewest mutations.
Species B and Species C most likely diverged from Species A since they both have more mutations than Species A.
Species B most likely evolved from Species C since they are closest to each other in terms of number of mutations.
Species C most likely diverged from Species A more recently than Species B since Species C has fewer mutations than Species B.

Answer 2

um this is kinda past my skill lvl srry I'm not even sure here lol

Answer 3

Start by looking at your species there, and comparing the numbers, make a chart kinda like this drawing below. Fewest mutations would be lower # dif.

Answer 4

And by compare I mean, for AB Look at the lines for A and for B. Start at each letter. Is the first letter the same in both or different? Then the second letter, etc.
