Protocol:
- Added 1 microliter of loading dye to ISSR PCR products
- Loaded onto gel for imaging
- ran at 60 volts for about an hour and a half
Analysis of Lupinus ITS Sequences
- Downloaded Lupine_MEC_2017 file from Canvas
- Opened file in geneious
- Trimmed then assembled forward and reverse DNA sequences
- Selected all consensus sequences and made an alignment using default parameters of Muscle.

Write Up Questions
- Yes, my tree had one clade with a support value above .85. They were somewhat close together, and they all seemed to be from populations that had yellow flowers.
- Yes, a few populations that had purple flowers belonged to the same clade as other purple-flowered populations
- I believe that although ITS sequences can distinguish populations somewhat, the differences in these sequences are not enough to draw solid conclusions phylogenetically. This is because a lot of sequences failed to be grouped into distinct clades with other sequences. As a result of this, it is hard to claim that the ITS is useful enough to group these differing color populations phylogenically.
