  1. 1. Multi-trait Branching Models with Applications to Species Evolution

    Författare :Daniah Tahir; Ingemar Kaj; Martin Lascoux; Asger Hobolth; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Markov models; branching processes; density dependence; discrete traits; species trees; diversification rates; diffusion approximation;

    Sammanfattning : This thesis provides an analysis of the evolution of discrete traits and their effect on the birth and survival of species using the theory of supercritical, continuous time Markov branching processes. We present a branching modeling framework that incorporates multi-trait diversification processes associated with the emergence of new species, death of existing species, and transition of species carrying one type of a trait to another.

  3. 2. Statistical genetic analysis of family data

    Författare :Benjamin H Yip; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Variance component; ascertainment; population-based family data; Generalized linear mixed model; binary trait; quantitative genetics;

    Sammanfattning : The importance of genetic determinants and risk factors of diseases has been consistently recognized in genetic epidemiology, which is one of the fastest growing areas in genomic medicine. Familial clustering is a common characteristic of genetic related phenotypes, providing vital insights into the etiology of diseases by establishing the relative contribution of genetic and environmental factors.

  4. 3. Statistical methodology for testing genetic association in family-based studies

    Författare :Gudrun Jonasdottir; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis is concerned with family-based studies of association between genetic markers and binary traits. A special point of interest in family-based association studies is to separate the within family correlation and the genetic effect common among all families in the study. LÄS MER

  5. 4. What Is the Problem of Gender? Mainstreaming Gender in Migration and Development Policies in the European Union
