Each raised pure [true] breeding sheep. Fences and grazing ranges were meticulously maintained. Characteristics of the breed include Black vs white wool. Long vs short stranded wool and Narrow vs wide muzzles.Muzzle widthe determined if sheep grazed mainly in the fields or could roam craggy hillsides. Both shepherds were bachelors. Both suddenly died mysteriously on the same day. By the time that other villagers noticed, both herds had co-mingled. In the following Spring there were several new lambs the F1 generation of the co-mingle and it appeared that they all belonged to O”Doherty. However, 3 years later, the not so true breeding O’Doherty lambs began birthing the F2 generation, and it was obvious to all of the descendant shepherds that a tri-hybrid cross had taken place among the F1 sheep. Fill in the following table of expected genotypes and phenotypes for the F2 generation.
