Genetic markers as instrumental variables [PDF]

Journal of Health Economics, 2016
The use of genetic markers as instrumental variables (IV) is receiving increasing attention from economists, statisticians, epidemiologists and social scientists. Although IV is commonly used in economics, the appropriate conditions for the use of genetic variants as instruments have not been well defined. The increasing availability of biomedical data,

Recurrent mass selection for upright plant architecture in common bean

Scientia Agricola, 2014
Plant with a more upright architecture offers many advantages to farmers. Recurrent mass selection (RS) programs for carioca type common bean have been implemented for the purpose of obtaining new lines that will generate the high yields that are ...

Genetic variability, heritability, and genetic advance of morphological, yield related and quality traits in upland rice (Oryza Sativa L.) genotypes at pawe, northwestern Ethiopia

Cogent Food & Agriculture, 2023
The rice production in Ethiopia is less than the world’s average due to the lack of varieties with high yield potential. Evaluation of genetic variability is important in the rice breeding program for the production of high yielding varieties.

Levels of genetic polymorphism: marker loci versus quantitative traits [PDF]

, 1998
Species are the units used to measure ecological diversity and alleles are the units of genetic diversity. Genetic variation within and among species has been documented most extensively using allozyme electrophoresis.

Invasion of Europe by the western corn rootworm, Diabrotica virgifera virgifera: multiple transatlantic introductions with various reductions of genetic diversity [PDF]

, 2008
The early stages of invasion involve demographic bottlenecks that may result in lower genetic variation in introduced populations as compared to source population/s. Low genetic variability may decrease the adaptive potential of such populations in their

Effects of Sex and Gender on Adaptation to Space: Musculoskeletal Health [PDF]

, 2014
There is considerable variability among individuals in musculoskeletal response to long-duration spaceflight. The specific origin of the individual variability is unknown but is almost certainly influenced by the details of other mission conditions such ...
