2. 1. Linkage maps in studies of genetic variation - examples from Beta vulgaris

   Author : Thomas Kraft; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytogenetics; Genetics; Beta vulgaris; Linkage maps; genetic variation; Genetik; cytogenetik;

   Abstract : Today, most studies of genetic variation utilise molecular markers, making it possible to detect variation at the DNA level. This has greatly facilitated studies of genetic variation in population and evolutionary genetics, systematics and transmission genetics. READ MORE

4. 2. Chicken Genomics - Linkage and QTL mapping

   Author : Per Wahlberg; Leif Andersson; Ruedi Fries; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; chicken; quantitative genetics; linkage map; QTL mapping; recombination; long-term selection; Z chromosome; selective sweep; SNP; Genetics; Genetik;

   Abstract : This thesis presents results from genetic studies conducted in the chicken (Gallus gallus). The domestication of chicken is believed to have been initiated approximately 7,000 – 9,000 years ago in Southeast Asia. READ MORE

5. 3. Genetic Analysis of Fat Metabolism in Domestic Pigs and their Wild Ancestor

   Author : Frida Berg; Leif Andersson; Maria Moller; Stefan Marklund; Sigbjörn Lien; Uppsala universitet; []
   Keywords : Genetics; Pig; Quantitative Trait Locus; Fat deposition; FAT1; Linkage map; RH map; Comparative map; Backcross; Identical by Descent mapping; Brown adipose tissue; UCP1; Genetik;

   Abstract : The domestication of the pig began about 9 000 years ago and many of the existing domestic breeds have been selected for phenotypic traits like lean meat and fast growth. Domestic pigs are phenotypically very different from the ancestral wild boar that has adapted to survive in their natural environment. READ MORE

6. 4. Phenomenological modelling of sensory integration phenomena using self-organized feature maps

   Author : Tamas Jantvik; Wlodzislaw Duch; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

   Abstract : The main contribution of the work presented herein is a method of transferring information from one lattice of artificial neural units to another. The essence of the present method consists of four parts: (1) the wrapping of the artificial neural lattice into a module that given an input to this lattice outputs normalized coordinates for the location of peak activity and the magnitude of the activity at that location; (2) the inter-module exchange of information being carried out by using the coordinates of the neuron that respond the strongest to the input given to the artificial neural lattice; (3) the concept of the transformation map which re-maps normalized coordinates from one module's output space on another's; and (4) fusion carried out by summation of activity fields induced by artificial neural lattices.

7. 5. Genetic dissection of multifactorial disease models in the rat

   Author : Hong Jiao; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Type 2 daibetes; Goto-Kakizaki rat; linkage analysis; quantitative trait locus; gene-gene interaction; mitochondrial sequence; parent-of-origin;

   Abstract : Type 2 diabetes (T2D) is characterized by two apparently distinct pathophysiologic defects - insulin resistance and a failure of the pancreatic Beta-cells to compensate for this resistance by appropriately increasing insulin secretion. There is strong evidence for an important role of genetics in both of these components. READ MORE
