Cloning horses may reveal insights into complex genetics

There are lots of beliefs about genetics. One of the very persistent notions is that when an individual is cloned, the clone is an exact phenotypic copy of the original. That is, the clone and original will be exactly the same in every way: ability, talents, preferences, athletic ability, and so on. However, inheritance and gene expression are much more complicated than that. Now, a new "experiment" may shed light on how things like epigenetics, environment, and quantitiative traits (like athletic performance) work. Check out this article on what a cloned racehorse is teaching us.
