	abstract = {Karyotype analysis, used for screening chromosomal anomalies in  humans and livestock, is being evaluated as a means of identifying sheep  carrying the Booroola fecundity gene. This has involved comparing the  chromosomes of metaphase spreads from animals heterozygous for the  Booroola gene (FecB+) to screen for numerical or physical abnormalities  between the chromosome pairs using Giemsa (GTG) banding. A number of  anomalies have been observed from 18 of 3 FecB+ rams and 4  FecB+ ewes. The anomalies were spread throughout most chromosomes, but  none were present in all karyotypes. No alteration in chromosome number  was observed. These preliminary results suggest that the Booroola  mutation is not the result of a major chromosomal alteration.  },
