There are 250–500 thousand of these in Texas, where many are reared as trophy animals to be shot by hunters.

[citation needed] The breeding of two crossbreeds of the same combination of breeds, creating an F2 cross, an animal that is still a 50–50 cross, but it is the second filial generation of the combination. [10] An F2 cross bred to an F2 cross creates an F3 cross. Similarly, an F2 animal bred to an F1 animal creates an F2b backcross.

They introduced new technologies in quantitative genetics, reproductive physiology, nutrition and housing that allowed them to select for the traits they wanted to be expressed in the breed. [3] The research flock was closed in 1974, and the breed was distributed to shepherds beginning in 1988. [4] The Rideau name is a common one in Ottawa. The ...
