Genetic recombination refers to the process by which two DNA  molecules exchange genetic information. The three types of genetic  recombination are crossing over, conservati â¦ ve site-specific  recombination and transpositional recombination.
This produces a crystal lattice, which is commonly known as 'ice'. Ice floats because it is about 9% less dense than liquid water. In other words, ice takes up about 9% more space than water, so a liter of ice weighs less than a liter water. The heavier water displaces the lighter ice, so ice floats to the top. One consequence of this is that lakes and rivers freeze from top to bottom, allowing fish to survive even when the surface of a lake has frozen over.
Small openings at the top of the ridge allow it to be used as a snorkel. This is unique to Parasaurolophus Amphibio, as is their surprising speed in the water. .  As a relatively simple creature to domesticate, Parasaurolophus Amphibio is one of the most common mounts I've seen on The Island. Its ability to run fairly fast for lengthy intervals makes it a solid mode of medium-range transportation, though it has almost no ability to defend itself or its rider. .
