Allelic melanism in American and British peppered moths.
Parallel evolutionary changes in the incidence of melanism are well documented in widely geographically separated subspecies of the peppered moth (Biston betularia). The British melanic phenotype (f. carbonaria) and the American melanic phenotype (f. swettaria) are indistinguishable in appearance, and previous genetic analysis has established that both are inherited as autosomal dominants. This...
متن کاملGenetics and the British insurance industry.
Genetics and genetic testing raise key issues for insurance and employment. Governmental and public concern galvanised the British insurance industry into developing a code of practice. The history of the development of the code, issues of genetic discrimination, access to medical information, consent and the dangers of withholding information and the impact on the equity of pooled risk are exp...
متن کاملPneumoviruses: Molecular Genetics and Reverse Genetics
Pneumoviruses are responsible for significant respiratory disease in their hosts and represent a major problemfor human and animal health. Pneumoviruses are members of the family Paramyxoviridae, subfamilyPneumovirinae and the virus particles consist of a negative-sense, nonsegmented RNA genome within a helical nucleocapsid structure enveloped in a lipid membrane derived from the ho...
متن کاملIndustrial melanism in British peppered moths has a singular and recent mutational origin.
The rapid spread of a novel black form (known as carbonaria) of the peppered moth Biston betularia in 19th-century Britain is a textbook example of how an altered environment may produce morphological adaptation through genetic change. However, the underlying genetic basis of the difference between the wild-type (light-colored) and carbonaria forms has remained unknown. We have genetically mapp...
متن کاملA Comprehensive DNA Barcode Library for the Looper Moths (Lepidoptera: Geometridae) of British Columbia, Canada
BACKGROUND The construction of comprehensive reference libraries is essential to foster the development of DNA barcoding as a tool for monitoring biodiversity and detecting invasive species. The looper moths of British Columbia (BC), Canada present a challenging case for species discrimination via DNA barcoding due to their considerable diversity and limited taxonomic maturity. METHODOLOGY/PR...
