From: Gene flow and population structure in the Mexican blind cavefish complex (Astyanax mexicanus)
Summary of the estimates of gene flowbased on Bayesian inferences of migration rates and population sizes using MIGRATE-N 3.2.6 among Astyanaxs mexicanus population clusters within each geographical region. The arrows represent directions of migration and the thicknesses are proportional to the M (the ratio of immigration rate and mutation rate). Populations are coded as follows: El Abra caves (O1 - O7); Guatemala (N1 - N2); Micos (N3), Chica (O8); Surface (S1 - S4). Asterisk denotes mixed populations.
