You Obtain the Following Sequence Data from a Group of Related

question 8

Short Answer

You obtain the following sequence data from a group of related populations: $\begin{array}{lllll}\text { Base \#: } & 123456789 & & \\\text { Ancestral sequence: } & A A T & \text { TCA } & \text { GGA } & \text { Descendant }&\text { population } \\\# 1: & A A T & \text { TCA } & \text { GGA } & \text { Descendant }&\text { population } \\\# 2: & A A T & \mathrm{CCA} & \mathrm{GAA} & \text { Descendant } &\text { population }\\\# 3: & \mathrm{AAT} & \mathrm{CAA} & \mathrm{GGA} & \text { Descendant }&\text { population } \\\# 4: & A \mathrm{AACA} G G &\end{array}$ Construct a phylogenetic tree that fits the data and requires the least amount of genetic change, in other words, t most parsimonious outcome. Indicate which genetic changes occurred, if any, that were passed down to descendant populations.
