gene linkage
DNA sequences that are close to each other along a chromosome are more likely to be inherited together. So there is a correlation between closeness and likelihood of being transmitted to the next generation of cells and organisms. If 10 people are standing close to each other in a line and water is thrown at a single person the people standing closest to that person are more likely to get wet.
Imagine a jar of jellybeans of different colors. You want to grab a handful of jellybeans 'cause they taste good. You look for a red jellybean and grab it with your hand. You get the red jellybean and all the adjacent jellybeans. The jellybeans closer to the red jellybean are more likely to be scooped up. There is a correlation between jellybean closeness and jellybean extraction.
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
