Do you think that the people who experience true love can be linked through their DNA (details inside)?

I’ve taken the idea from “The One” by John Marrs. Here’s how he explains in pseudo-scientific terms the idea:
“We have roughly 100 trillion cells in our bodies and inside each of then are 2 metres of DNA – if you unravelled them all, they’d stretch to the sun and buck a hundred timed, and the sun is 98 million miles away from Earth. Women produce pheromones and men have receptors thay bind the pheromone molecules, and that can create an attraction between the two. [What if] when certain people are brought together there’s a variable genes inside us that allows both sexes to produce pheromones and have receptor genes. [...] It’s actually intergenerational Matches that have helped to cause a drop in birth rates around the world.”
