 In Ethiopia , there are several varieties of sheep landrace . Attempts have been made to classify the sheep based on factors such as tail shape and wool type , and H. Epstein made an attempt at classifying them this way by dividing the breeds into 14 types based on those two factors . However , in 2002 , further genetic analysis revealed that there are only four distinct varieties of Ethiopian sheep : short @-@ fat @-@ tailed , long @-@ fat @-@ tailed , fat @-@ rumped , and thin @-@ tailed .
