  1. 1. Genome-wide association studies on body weight and component traits in an intercross of two divergently selected chicken lines

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Yiwen Chen; [2021]
    Keywords : Genome-wide association study; Advanced Intercross Lines; Virginia chicken lines; artificial selection;

    Abstract : Here we present the genome-wide association study of body weight at 8 weeks of age based onthe advanced intercross pedigree of two chicken lines gone through bi-directional selection.With improved marker density (~3M SNPs) and larger sample size (2667 individuals from F2-F15), 34 loci with suggestive significance are detected, of which 18 loci are novel, and the rest17 loci are consistent with the results of previous quantitative trait locus mapping studies onthis trait with smaller number of genetic markers and fewer individuals.

  3. 2. Kors och tvärs : en vision för urban grönska i förtätningen längs Kontinentalbanan i Malmö

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Sara Bauer; My Söderberg; [2019]
    Keywords : landskapsarkitektur; grönstruktur; urban grönska; förtätning; överdäckning; Kontinentalbanan; Malmö; Sofielunds industriområde; snabbcykelstråk;

    Abstract : Tänk om en av Malmös stora barriärer, den järnväg som kallas Kontinentalbanan, skulle överdäckas och därigenom skapa möjlighet till ett grönstråk som förenar omgivande stadsdelar? Denna visionära tanke är startskottet på vårt examensarbete och det är därifrån vi har tagit avstamp i arbetet. Syftet med examensarbetet är att med landskapsarkitektur, och fokus på grönstrukturen, undersöka och visa på hur Malmö skulle kunna utvecklas om järnvägen som barriär försvinner. READ MORE

  4. 3. Domestication related genotype on ADRA2C - a determinant of fear response in chickens?

    University essay from Institutionen för fysik, kemi och biologi; Tekniska högskolan

    Author : Amir Fallahshahroudi; [2012]
    Keywords : Chicken; Fearfulness; Genetics; Domestication; ADRA2C;

    Abstract : White Leghorn (WL) breed is homozygous for an allele on the α2C-AR gene while the Red Junglefowl (RJF) is mostly heterozygous for that. The gene is also hypermethylated in WL. READ MORE

  5. 4. Geographical and Environmental Impacts of Climate Change in the Arctic Legal Regime: Towards a Comprehensive Legal Order for Balancing Environmental Governance and International Trade & Commerce Interests

    University essay from Lunds universitet/Juridiska institutionen

    Author : Tafsir Matin; [2012]
    Keywords : Soft law; Hard law; Arctic Council; strict liability; absolute liability; zero-discharge policy; Commercial implications; Geographical impacts; Environmental impacts; Climate Change; Arctic States; Intercross; Balancing interests; New legal regime; Multilateral agreements; Joint contingency plans; Arctic national legislations; International Conventions.; Law and Political Science;

    Abstract : The thesis aims at supplementing a critique of the existing international instruments, regional responses and national legislation of the Arctic related to marine environmental protection. With this aim in view, the thesis satisfies its objective by proposing a Bipartite “Arctic Council” acting as a conglomeration of the Arctic States and the Flag States with a hybrid “Arctic treaty”, which is an interplay of international and regional response.

  6. 5. A mutation in the TSHR gene - how does it affect social and fear related behaviours in chickens?

    University essay from Biologi; Tekniska högskolan

    Author : Frida Svemer; [2012]
    Keywords : Domestication; Chicken; Fear; Dominance; Thyrotropin; Thyroid stimulating hormone receptor; TSHR;

    Abstract : Thyroid hormones are well known important to be in development and growth in birds and that signaling of thyrotropin (TSH) regulates the photo induced seasonal reproduction. A mutation at the thyroid stimulating hormone receptor (TSHR) gene in domestic breeds of chicken could be involved in the release of the photoperiodic regulation. READ MORE
