The sporophyte of a fern is determined to be heterozygous at 50% of its genetic loci. If the individual bisexual gametophytes produced by this fern are only capable of fertilizing themselves, what percentage of heterozygous loci would you expect in the sporophyte plant formed from a single gametophyte?

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
