"A recessive trait is like a gene that doesn't show up very often. So, since albinism is a recessive trait, that means albinos are rare. And even if both parents carry the right gene(s), not all their offspring will be albino, only one in a few. That is another reason why albinos are so rare."
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.
