Pricing Dynamics in the US Hemp Market: A Vertical Price Transmission Analysis of the Hemp Value Chain

open access: yesAgribusiness, EarlyView.
ABSTRACT The US hemp market is a new and nascent industry that has been devoid of research for about half a century. This study examined the effects of exogenous shock on price at each phase of the value chain—Farm (hemp biomass), and its impact on prices at other phases of the value chain—Intermediary Processor (crude cannabidiol hemp) and Final ...

Linkage disequilibrium and recombination rate estimates in the self-incompatibility region of Arabidopsis lyrata [PDF]

open access: yes, 2007
Genetic diversity is unusually high at loci in the S-locus region of the self-incompatible species of the flowering plant, Arabidopsis lyrata, not just in the S loci themselves, but also at two nearby loci.

Price Transmission and Leadership in the Global Poultry Market: Results From Parametric and Nonparametric Approaches

open access: yesAgribusiness, EarlyView.
ABSTRACT Brazil and the United States account for more than 40% of global poultry exports, with China and South Korea among their major destination markets. This study examines price transmission and market linkages between Brazil and the United States using monthly poultry export price data from January 1990 to December 2024. It also assesses which of

Linkage Disequilibrium and Association Analysis

open access: yes, 2021
This chapter considers allelic association to be association occurring between alleles at different loci. Allelic association can occur between linked or unlinked loci. There are many different measures of linkage disequilibrium.

Including copy number variation in association studies to predict genotypic values

open access: yes, 2010
The objective of this study was to investigate, both empirically and deterministically, the ability to explain genetic variation resulting from a copy number polymorphism (CNP) by including the CNP, either by its genotype or by a continuous derivation ...

Long-range linkage disequilibrium in French beef cattle breeds

open access: yesGenetics Selection Evolution, 2021
Background Linkage disequilibrium (LD) is a key parameter to study the history of populations and to identify and fine map quantitative trait loci (QTL) and it has been studied for many years in animal populations.

Genetic Risk and High Burden of Depression and Suicide in the Maya‐Mestizo Population of Yucatán, México

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Major depression and suicide are critical public health concerns, particularly in underrepresented populations with unique genetic and sociocultural contexts. The Maya‐mestizo population presents the highest suicide rates in the country but remains understudied in psychiatric genetics. This study evaluated the association between three genetic

Decay of linkage disequilibrium within genes across HGDP-CEPH human samples: most population isolates do not show increased LD

open access: yesBMC Genomics, 2009
Background It is well known that the pattern of linkage disequilibrium varies between human populations, with remarkable geographical stratification.

Similar patterns of genetic diversity and linkage disequilibrium in Western chimpanzees (Pan troglodytes verus) and humans indicate highly conserved mechanisms of MHC molecular evolution

open access: yesBMC Evolutionary Biology, 2020
Background Many species are threatened with extinction as their population sizes decrease with changing environments or face novel pathogenic threats.

Assessment of Genetic Correlations Between Tobacco or Alcohol Use and Neurodegenerative Diseases Using East Asian Genetic Ancestry Genome‐Wide Association Study Results

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Alzheimer's disease (AD) and Parkinson's disease (PD) are the most prevalent late‐onset neurodegenerative diseases worldwide. Both are influenced in part by genetic factors and are currently incurable. Tobacco and alcohol, the two most common substances used among the general adult population, are potential AD/PD risk factors and are also ...
