Fig. 3From: The roles of hybridization and habitat fragmentation in the evolution of Brazil’s enigmatic longwing butterflies, Heliconius nattereri and H. hermathenaDeleterious mutation loads in Heliconius nattereri and H. hermathena. a Derived allele frequency spectra in the Santa Teresa H. nattereri population, its close relative H. pardalinus, and H. melpomene melpomene. b Derived allele frequency spectra from H. erato and H. hermathena populations with the largest sample sizes.
