Frequency changes of GDF9-alleles among the Norwegian White Sheep AI rams. Frequency change in the GDF9 allele c.1111A in NWS AI rams born in 1990-2009. The number of genotyped rams per birth year is presented by bars. The period 1983 – 1989 is omitted from the figure due to low numbers of rams per year (3 AI rams per year in average).
