1. A method of increasing the genetic progress of a line or breed of swine within a genetic nucleus comprising the steps of:

  • providing a boar from a genetic nucleus and a sow from a genetic nucleus, wherein said boar and said sow are from a line or breed within said genetic nucleus and wherein said line or breed of said boar and said sow are the same line or breed;

    collecting a semen sample from said boar;

    sorting said semen sample into at least two subpopulations of sperm cells, wherein at least 80% of a first subpopulation bears X-chromosomes or Y-chromosomes;

    inseminating said sow with sperm cells from said first subpopulation to produce offspring from said sow;

    genotyping said offspring to identify one or more genetic markers;

    selecting one or more of said offspring as a parent in the line or breed in the genetic nucleus based on the one or more identified genetic markers.
