I got to the part in bold and I have no idea where to go fromhere.
Step 1:Find the pair with the smallest distance.
Step 2:Join them in one group and draw those branches.
Step 3:Compute average distance between this group and all othertaxa one-by-one and create new table with those values.
Step 4:Repeat Steps 1 to 3 using the new distance matrix.
Characters | A | B | C | D | E | F | G |
A | - | | | | | | |
B | 12 | - | | | | | |
C | 8 | 7 | - | | | | |
D | 37 | 26 | 2 | - | | | |
E | 17 | 41 | 35 | 30 | - | | |
F | 28 | 21 | 5 | 11 | 19 | - | |
G | 42 | 16 | 15 | 32 | 46 | 10 | - |
Based on above data, find the first two characters with theshortest distance and draw those branches with the respectivedistances on the branches below according to the example given inclass or online. This should be your first two branch tips.
C and D is the pair with the shortest distance as it is 2 units.A sub tree will be drawn with the branch point half way between thetwo given units. Each branch is 1 unit as this is 2 units dividedequally and each point is 1 unit away from the center node.
Recalculate distances based on the combination of the lastcharacters. This first table has been partially filled out for you.Determine and enter the missing values. (You need not fill out theboxes above the dashes as they are mirror values to the below-dashvalues.)
| A | B | CD | E | F | G |
A | - | | | | | |
B | 12.00 | - | | | | |
CD | 22.50 | (7+26)/2 = 16.5 | - | | | |
E | 17.00 | 41.00 | 32.50 | - | | |
F | 28.00 | 21.00 | (5+11)/2 = 8 | 19.00 | - | |
G | 42.00 | 16.00 | (15+32)/2 = 23.5 | 46 | 10.00 | - |
Draw the next branch pair based on the shortest distance of yournewly determined values and label each branch with its length andeach tip with its character.
