Itâs no secret that medical school is expensive. In 2013â14, the annual tuition and fees for public medical schools averaged $31,783 for in-state residents and $55,294 for non-residents. Meanwhile, the average private school tuition came in at $52,093 and $50,476 for residents and non-residents, respectively, according to Association of American Medical Colleges.
1997: Dolly the sheep is cloned. Dolly, who was created at the Roslin Institute in Edinburgh, was actually born on 5 July 1996 although her arrival has only just been revealed. Dolly is the first mammal to have been successfully cloned from an adult cell. Previous clonings have been from embryo cells.
A cross-bred ewe suckles her lamb, which was the first of the 2008 spring lambing at a farm in Coventry, England. As with other mammals, domestic sheep reproduction occurs sexually. Their reproductive strategy is very similar to other domestic herd animals. A flock of sheep is generally mated by a single ram, which has either been chosen by a farmer or has established dominance through physical contest with other rams (in feral populations). Most sheep have a breeding season (tupping) in the autumn, though some are able to breed year-round. Largely as a result of the influence of humans in sheep breeding, ewes often produce multiple lambs.
