An HMM-Based Comparative Genomic Framework for Detecting Introgression in Eukaryotes
Figure 9
The phylogenetic network used in our analyses and the two parental trees.
The phylogenetic network (a) captures introgression from M. spretus to M. m. domesticus. The red and blue lines illustrate two possible gene genealogies involving no introgression (blue) and introgression (red). The parental tree in (b) captures genomic regions with no introgression, while the parental tree in (c) captures genomic regions of introgressive descent.
