Stud rams used fall 2023

Anchorage 1856/22 BW  is a white ram. His  “white” dam, Anchorage 1573/18,  was the daughter of  a ram from another flock who was thought to be “white” but who, put to two Anchorage ewes also thought to be “white,”  sired twins on each, one white and one colored. Conclusion: the sire of 1573 had to have a color allele at the agouti locus that had escaped notice for generations; likewise, her dam must have had a single recessive color allele that no one would have guessed to be present.  Therefore, his progeny had be be denoted  as BW. 

In  COGNOSAG lingo,  the maternal grandsire would be called in retrospect  Awt Ax E+ E+ [Here Ax means there's a "color allele" at agouti,  but we don't know what it is.] His daughter, 1573,  would be written Awt A_ E+ E+ where A_ indicates we can’t say  whether the second allele is Awt or Ax. The stud ram 1856/22 would be described like his dam Awt A_ E+ E+.  Recall that one Awt at agouti is all that’s needed to make the sheep look white, while to make the sheep colored two color alleles are required.
