Association of Some Qualitative and Quantitative Traits in Chickens

open access: yesPoultry Science, 1965
Abstract INTRODUCTION INVESTIGATIONS of possible linkages between various qualitative and quantitative traits in the fowl and the importance of such have resulted in some conflicting reports. More evidence is needed to demonstrate the existence or non-existence of some of these associations and to show their relative importance.

Correlation, regression and cluster analyses on yield attributes and popping characteristics of popcorn (Zea mays L. everta) in derived savanna and rainforest agro-ecologies of Nigeria

open access: yesActa Agriculturae Slovenica, 2021
Information on the genetic and agronomic relationship among the crop characters is important for the breeding programs. This study aimed at determining the relationship among grain yield, popping expansion and other agronomic characters in 19 popcorn ...

Genotyping of Flax Genetic Resources by Mirna-Based Molecular Markers and Morphology

open access: yesAgriculture, 2015
MicroRNAs (miRNAs) are a class of non-coding RNAs about 20-24 nucleotides long. They play an important role in the gene regulation at the post-transcriptional level. They affect the plant genome response to environmental stress. The miRNA-based molecular

Joint association analysis of bivariate quantitative and qualitative traits [PDF]

open access: yesBMC Proceedings, 2011
Univariate genome-wide association analysis of quantitative and qualitative traits has been investigated extensively in the literature. In the presence of correlated phenotypes, it is more intuitive to analyze all phenotypes simultaneously. We describe an efficient likelihood-based approach for the joint association analysis of quantitative and ...

Morphoagronomic genetic diversity in american wild rice species

open access: yesBrazilian Archives of Biology and Technology, 2008
To characterize the genetic variability among species and populations of South American wild rice, eleven populations of Oryza glumaepatula, seven of O. grandiglumis, four of O. latifolia and one of O. alta, from Brazil and Argentina, were evaluated.

Considerations on the evolution of qualitative multistate traits [PDF]

open access: yesActa Biotheoretica, 1979
Simple models for the evolution of qualitative multistate traits are considered, in which the traits are permitted to evolve in time-dependent versus speciation-dependent fashion. Of particular interest are the means and variances of distances for these traits in evolutionary phylads characterized by different rates of speciation, when alternative ...

Testing Gene-Gene Interactions Based on a Neighborhood Perspective in Genome-wide Association Studies

open access: yesFrontiers in Genetics, 2021
Unexplained genetic variation that causes complex diseases is often induced by gene-gene interactions (GGIs). Gene-based methods are one of the current statistical methodologies for discovering GGIs in case-control genome-wide association studies that ...
