Over the entire genome the loss is about 50% per generation. In this example the tall version of the height gene is lost to later generations. Lets say we liked the short mushrooms so we saved that one and took a spore print for later. Obviously the strains with two short copies will be short and the ones with two tall copies will be tall. Sticking to our height gene example, you could get two short copies, two tall copies or one of each. Now, when you do multispore from a single mushroom you randomly get a mix of all the genes. If heterozygosity is high, you have one of each which may result in medium mushrooms unless one of the height genes is dominant. For example, if there is a single gene for height, you might have a version that gives short mushrooms and a version that gives tall mushrooms. Its the same gene location with the same basic function, but different versions. This basically means that most or all of each pair of genes in the mushroom are different from each other. Now consider a wild collection of Psilocybe cubensis with a high heterozygosity. Here's a simple explanation of selective breeding in mushrooms: Well each spore develops monokaryotic mycelium, when it combines with another one they share genetic information, form dikaryotic mycelium, and only then can form fruits. There are other types of seed banks and libraries around the world some of them have a broader biodiversity focus and may include fungus. So it's safer to keep the seed vault a fungus-free zone. Seed vaults are very careful about contamination- it would be awful if the seeds that came out of the vault post-apocalypse were already contaminated with some type of fungal blight. Edit: See /u/Awkward_Tradition's extremely informative comments below- they have more experience with fungal storage than I do.Ģ) There are good fungi that are helpful for the ecosystem, but there are also a lot of bad fungi. Think of it like taking cuttings from a fruit tree. People do grow some mushrooms as food crops, but Spitsbergen is for plant seeds.ġ) The optimal storage conditions for crop seeds and fungus spores are different also, most mushroom cultivars are spread by transplanting pieces of mycelium, not the spores.

One of the fundamental assumptions in future(s) studies is that the future is plural rather than singular, that is, that it consists of alternative future(s) of varying degrees of likelihood but that it is impossible in principle to say with certainty which one will occur. If history studies our past and social sciences study our present, what is the study of our future? Future(s) Studies (colloquially called "future(s)" by many of the field's practitioners) is an interdisciplinary field that seeks to hypothesize the possible, probable, preferable, or alternative future(s).
