hhul Incompatibility of DNA variants with a coalescence tree with six leaf nodes
hhul The table of variants is identical
with that in Figure 5.2smc;
as
before, the leaf nodes are designated
1 - 6 and the order of variant positions a
- e is arbitrary. The tree in Fig.
5.2 has been redrawn by moving the #3 leaf node
from below (1+2) to below (4+5). Mutations
at SNPs a, c, & e can be
mapped on the tree with only one change (red
stars). SNPs b & d cannot be
placed on the tree without at least two changes each,
if this is the correct tree.
HOMEWORK:
Show a modified table of variants that modifies SNPs ##
1, 3, & 6 in which the tree shown can
be explained with only one mutation each at
SNP sites a - e.
