afs-71227	Korkman, Nils	On the inheritance of female sterility in cattle	1947	7	.pdf	application/pdf	2754	160	59	For this reason the cows within the separate herds were divided into age groups, cows born in the years 1916—18 being referred to one group, those born 1919—21 to another etc., always maintaining a range of 3 years. Gregory, Regan and Mead (5) show than in mate- rial investigated by them, sterility is more frequent in cows with a higher inbreeding coefficient than in cows with a lower one, and the same authors (Mead, Gregory and Regan (10)) further establish that by inbreeding to certain sires, the daughters have a greater tendency to sterility than cases in which there was outbreeding.	cache/afs-71227.pdf	txt/afs-71227.txt
