This thesis provides a brief literature review on adaptive introgression and radiations as well as background information pertaining to the monkeyflower radiation of Southern California. Utilizing genomic analysis methods, this thesis investigates the 100 kilobase region surrounding the MaMyb2 locus. Through this analysis, it is shown that the region surrounding MaMyb2 in the red ecotype of M. puniceus is genetically more similar to Mimulus rutilus, rather than to the accepted donor taxa of the introgressed gene, Mimulus aridus. This thesis also discusses the surrounding genomic landscape and its evolutionary implications.en-USCC BY-NC-ND 4.0MimulusIntrogressionEvolutionGenomicsMaMyb2Thesis/Dissertation0000-0001-6489-9746
