Supplementary Figure 1. Glover et al. 2013. Hybrids between common and Antarctic minke whales are fertile and can back-cross.

Bayesian clustering analysis computed when the number of genetic clusters is set at 2 (top figure) through to 6 (bottom figure). Each vertical line represents a single individual (which can be admixed), and each colour a genetic cluster. Columns 1-91 = B. a. acutorostrata, 92- 186 = B. a. scammoni, 187-277 = B. bonaerensis, 278-286 = B. a. unnamed subspecies =

“Dwarfs”, 287 = B. bonaerensis long-distance captured in the Arctic in 1996 , 288 = first documented hybrid between minke whale species captured also in the Arctic in 2007 , 289 = mother hybrid minke whale captured in 2010 documenting first pregnant hybrid between minke whale species, 290 = fetus for individual 289 representing the first documented example of back-crossing between any whale species.

In this second phase (3S 2 ) we switched to other species and even though some important changes were made, the primary aspects of the experimental design, data collection

The overall objectives of the trial were to establish a new modus operandi for the 3S-group with our new target species (Minke whales, Northern Bottlenose whales and Humpback

This variablilty in lipid levels in muscle and blubber at different sites is similar to that found in other balaenopterid whales indicating that also for common minke whales,
