What are the different ways fungal spores can be dispersed?
stealth61 [152]

Answer:

Explanation:

The spores of some fungi are dispersed in water or on the surface of water. The chemical composition of the wall of these spores makes them "non-wettable" so they won't sink. The spores are carried along on the surface of the water like little boats. Water in the form of raindrops can disperse spores in a different way. While gravity is not a primary means of spore dispersal, evolutionary adaptations have been required of many fungi to overcome gravitational effects for effective spore dispersal. SPORE DISPERSAL BY WIND Dispersal of fungal spores by wind is by far the most common method for terrestrial fungi.

In the given situation, both parents are homozygotes.
