Characteristics of genetic epidemiology and genetic models for vitiligo
Journal of the American Academy of Dermatology, 2004Vitiligo occurs with a frequency of 0.1% to 2% in various populations and is classified into several subtypes by its clinical presentation. Although genetic factors are thought to be involved in the cause of vitiligo, the genetic models for different phenotypes of vitiligo are unknown.Our purpose was to explore potential genetic models for different ...

Adapting genetic regulatory models by genetic programming
Biosystems, 2004In this paper, we focus on the task of adapting genetic regulatory models based on gene expression data from microarrays. Our approach aims at automatic revision of qualitative regulatory models to improve their fit to expression data. We describe a type of regulatory model designed for this purpose, a method for predicting the quality of such models ...

Genetic algorithm for system modelling
2017 9th International Conference on Electronics, Computers and Artificial Intelligence (ECAI), 2017The process of modeling of a real system usually implies an iterative approach where an initial model is incrementally modified in order to increase its accuracy with regard to available experimental data. Many approaches are discussed in the literature, among which some are based on Artificial Intelligence techniques.

Genetic modeling of feed intake
Journal of Animal Science, 2015ABSTRACT With the development of automatic self-feeders and electronic identification, automated, repeated measurements of individual feed intake (FI) and BW are becoming available in more species. Consequently, genetic models for longitudinal data need to be applied to study FI or related traits.

Schizophrenia: a Study of Genetic Models
Human Heredity, 1979The likelihoods of observing 25 four-generational families of schizophrenics comprising 1,333 individuals have been calculated on the basis of 12 different genetic models and one control 'sporadic' model. The control model gave a log10 likelihood (L), of -240.92. Five of the genetic models were definitely excluded as incompatible with certain pedigrees.

Genetic models of reading disability
Behavior Genetics, 1980Test data collected on 133 reading-disabled (RD) children and their nuclear families who participated in the Colorado Family Reading Study were subjected to segregation analysis utilizing the technique of Elston and Yelverton (1975) for a continuous phenotypic measure.

Abstract The “Fisherian” optimality approach determines the optimal combination of trait values but not the evolutionary trajectory nor, in general, the variation to be expected about the optimal combination. Invasibility analysis is also primarily concerned with the Evolutionarily Stable Strategy (ESS) values; though assuming clonal ...

Alcohol and genetics: New models
American Journal of Medical Genetics, 2002AbstractAlcoholism is a complex genetic trait; susceptibility is influenced by multiple genes of small effect. To pursue mechanistic studies, genetic animal models have been used. These models are partial, each addressing one or more of the contributing traits rather than the disease as a whole.

Abstract Certain features of the epidemiology of neural tube defects are consistent with a genetic component in their aetiology. First, concordance rates for neural tube defects are significantly higher in twin pairs of like sex than in twin pairs of unlike sex (Chapter 11). Thus, it is likely that monozygotic twins are concordant for

Genetic models in applied physiology
Journal of Applied Physiology, 2003We are in a genomic revolution, and many of the major advances in applied physiology are based on discoveries made with genetic model systems. These model systems provide not only an in-depth understanding of normal human physiology but also serve as models of human disease.
