  • Makes me think of this: https://en.wikipedia.org/wiki/Dentition#Dental_formula

    Teeth can tell you a lot about an animal. Their size, shape, number etc can tell you what it eats or how it eats or how much it eats. Dental formula can give you clues for how animals are related to each other. If two different animals have the same dental formula then maybe they share a common ancestor or have a similar diet. If two animals are already very similar but have different dental formula then maybe they’re only very distantly related or there’s been some convergent evolution elsewhere.
















  • Seedless grapes already exist, but I suppose you could now insert the gene into other plants/varieties to make those seedless as well.

    I’m thinking more about how big ag companies could use this to prevent farmers from saving seeds/propagating a copyrighted variety (though I don’t know if that’s common with any crops where the seed itself isn’t the end product) or maybe more charitably, preventing their copyrighted plants from cross pollinating neighboring fields of the same species (e.g. ruining that neighbor’s non-gmo status).

    Finally, this could be useful if it can be “switched on” i.e. by deliberately polluting an invasive plant’s gene pool with this gene and then switching it on to stall the invasive’s population growth. But I think most invasives are perennials, so would still need to be removed some other way.
