this doesn't look like sonic the hedgehog to me, what the forget is going on who named these things
When the gene fails and mutates it causes the body to form incorrectly, and in certain fly embryos, it gave them spikey parts, which made them look like a hedgehog.
There are three hedgehog genes in vertebrates, two named after actual types of hedgehog, and the one named after Sonic.
There's also a 'tiggywinkle hedgehog gene' found in zebrafish, named after a character from Beatrix Potter's books.
