The quantitative genetic basis of sex ratio variation in Nasonia vitripennis : a QTL study [PDF]

open access: yes, 2010
Our understanding of how natural selection should shape sex allocation is perhaps more developed than for any other trait. However, this understanding is not matched by our knowledge of the genetic basis of sex allocation.

Assessment of Genetic Diversity and Conservation in South African Indigenous Goat Ecotypes: A Review

open access: yesAnimals, 2022
Goats were amongst the first livestock to be domesticated more than 10,000 years ago for their meat, milk, skin, and fiber. They were introduced to Southern Africa by migrating nations from Central Africa to the south.

Genetic variation of metabolite and hormone concentration in UK Holstein-Friesian calves and the genetic relationship with economically important traits [PDF]

open access: yes, 2009
The decline of dairy cattle fertility worldwide remains a major concern, with conception rates to first service commonly below 40%. The length and severity of negative energy balance postpartum are unfavorably correlated with fertility, suggesting that ...

Common Genetic Variation and the Control of HIV-1 in Humans [PDF]

open access: yes, 2009
To extend the understanding of host genetic determinants of HIV-1 control, we performed a genome-wide association study in a cohort of 2,554 infected Caucasian subjects.

Oracle selection provides insight into how far off practice is from Utopia in plant breeding

open access: yesFrontiers in Plant Science, 2023
Since the introduction of genomic selection in plant breeding, high genetic gains have been realized in different plant breeding programs. Various methods based on genomic estimated breeding values (GEBVs) for selecting parental lines that maximize the ...

Genetic Variation in the Response to Vaccination

open access: yesPublic Health Genomics, 2007
Vaccines are the most powerful means to prevent and diminish the burden of infectious disease. However, there are limitations to their use: vaccines are not yet available for all infectious diseases (including human immunodeficiency virus and respiratory syncytial virus), they sometimes lack efficacy, the response to vaccination is limited by maternal ...

Spatiotemporal patterns of genetic variation for growth and fertility in Scots pine [PDF]

open access: yes, 2011
Genetic testing plays an important role in tree breeding. Understanding basic genetic parameters for growth and fertility is a prerequisite for developing a successful breeding strategy to balance between short- and long-term gains.

Discovery of Sexual Dimorphisms in Metabolic and Genetic Biomarkers [PDF]

open access: yes, 2011
Metabolomic profiling and the integration of whole-genome genetic association data has proven to be a powerful tool to comprehensively explore gene regulatory networks and to investigate the effects of genetic variation at the molecular level.
