In general, most people view dna as a recipy that's written all over the body, but in the more professional fields people also know that tha's not the whole truth, as your entire body is made out of a lot of different dna-matchups containing dna from most of your family line. It is possible for an individual to have the exact hand as their father does, which actually caused some havoc when a father and son was involved in a murdercase, where they both had the same hand-dna. The term for this is called chimeric dna, and allows dna-cells from a baby to crawl back through a mothercake and influencing the mothers dna. It's all a very complicated machinery, adapt at mixing humans. So to answer the question asked by the meme, if the fingers were held at an angle it might be possible for two fingers to entwine into one finger :D
