Conventional breeding schemes for dairy cattle are based on phenotypic information obtained from individuals and/or their relatives and progeny testing of the young bull candidates. The genetic model used in the evaluation process of the animals does not assume the underlying genes of the quantitative traits to be known. Knowing the chromosomal areas or actual genes affecting the traits would a...

In an era in which schools are expected to achieve more for their students, many teachers remain frustrated by the increasing results-driven demands made on them. A facet of teacher work life in which many feel disempowered is addressed in this study—the regular infringement of outside intrusions into the classroom learning environment. A stratified random selection of teachers in the Canadian ...

Cytogenetic analysis of short-term cultures was carried out on 109 lipomas from 92 patients. Clonal chromosomal abnormalities were pres ent in 50% of the tumors analyzed. Based on the results, three main Cytogenetic groups were identified and included: (a) tumors with normal karyotypes, (b) tumors with abnormalities involving region ql3-15 on chromosome 12, and (c) tumors with other clonal aber...
