Question 10

Escovopsis fungi are parasites of the fungal gardens cultivated by Attine ants. The cultivated fungi are passed vertically through the generations as each queen takes the cultivar to her new colony. By contrast, Escovopsis species transfer horizontally from one colony to another. Despite these different transfer methods, the phylogenies of the ants, their cultivated fungus, and the parasite species are very similar. Why does the Escovopsis phylogeny resemble the ant and cultivated fungi phylogenies?

Accepted Answer

A)  Escovopsis fungi can undergo sexual reproduction with the cultivated fungal species 
B)  Transfer of Escovopsis to a new colony occurs only once the colony is well established 
C)  A small amount of Escovopsis is vertically transferred, so the phylogeny resembles the vertically transferred cultivated fungal species. 
D)  Escovopsis is subjected to selective pressure from the evolving ant and cultivated fungal species 
A)  Escovopsis fungi can undergo sexual reproduction with the cultivated fungal species 
B)  Transfer of Escovopsis to a new colony occurs only once the colony is well established 
C)  A small amount of Escovopsis is vertically transferred, so the phylogeny resembles the vertically transferred cultivated fungal species. 
D)  Escovopsis is subjected to selective pressure from the evolving ant and cultivated fungal species
