Patterns of allele distribution in a hybrid population of the Cryptococcus neoformans species complex.

The divergence between C neoformans and C deneoformans genomes has likely created co-adapted allelic combinations, with their co-segregation in hybrid offspring imparting a significant fitness benefit. However, the diversity of genotypes recovered here in a single hybridisation event indicates the enormous capacity of AD hybrids for adaptation and diversification.
