The genotypic structure of parasite populations is an important determinant of ecological and evolutionary dynamics of host-parasite interactions with consequences for pest management and disease control.

We here analyze the natural genotypic distribution of Crithidia bombi. a trypanosomat... https://www.lisamalloryphoto.com/product-category/sleeping-mask/
