The world-famous hamburger chain, Peat's Patties, has been accused of selling hamburgers that are not actually made
from beef. After multiple complaints, the United States Food Safety and Inspection Service obtained hamburger
samples from Peat's Patties (Peat's Sample A and Peat's Sample B), extracted the DNA from the meat, conducted
genetic sequencing and used the resulting sequences, along with DNA sequence data from other animals, to build a
phylogeny that shows the relationship of Peat's Patties meat to other animals. Use the phylogeny below to determine if
Peat's Patties is guilty of using alternative meat sources in their burgers.
Bison
Cow
Goat
Sheep
2. What type of meat is Peat's Patties using in their hamburgers?

Expert Solution
Step 1: Peat's patties hamburgers made from
Peat's Patties hamburgers appear to be made from cow flesh based on the phylogeny provided. To determine, we need to find the position of cow in the phylogeny provided. Looking at the phylogeny, we can see that cow is directly connected to bison, which suggests that they are closely related. Therefore, it is likely that Pete's Patties hamburgers are made from cow meat.
