Megan Rolf (Kansas State University): Genetic antagonisms can be hard to break if that genetic correlation is really strong. But there are two ways that you can begin to overcome genetic antagonisms. The first is selecting for both of those traits simultaneously. So, if we wanted to increase weaning weight and moderate mature size, we would select for those two traits separately to try and control mature size while still increasing growth rate. The second option is to use a selection index where both of those traits have been included in the index and have appropriate economic weightings to help balance those traits in a selection.
