1959 the Russian scientist Dmitri Belyaev began one of the most intensive experiments into domestication, in spite of intense political problems in the past. Starting with a group of wild foxes he tested categorised them into groups based on how they reacted to humans and allowed the most approaching, and consequentially the tamest, to mate. By continuing this practice with the resulting offspring for many generations Belyaev eventually had a group of foxes that would not only approach humans but actively seek their attention through nuzzling and wagging their tails.
Sound familiar? Well it is not the change in the fox’s behaviour that is the most startling aspect of this experiment, but their change in appearance. The foxes seem to not only have taken on behaviour similar to a dog’s but also a similar appearance. The colouration of the fox’s fur and the shape of their skulls had changed to be more dog like and their ears even became floppy. This change of appearance is so surprising as Belyaev did not breed based on appearance merely behaviour. The effects shown in this change in appearance are evidence of a phenomenon known as pleiotropy. Pleiotropy is the presence of genes that affect more than one trait. In this example the allele of the gene that caused tameness also caused this striking change in appearance.

“The basic plan of the Marcus Beach house was sketched out in the sand during an early site visit: a simple diagram of two pavilions placed either side of a venerable Morton Bay ash that stands as a cynosure to the scale, proportions and life of the house around it.”
While your institution of learning might be plenty interesting by muggle standards, what could be better than attending a school of magic? Unfortunately, their financial aid is lacking…
