  1. 1. Skillnader mellan granindivider gällande initieringsfrekvens för somatisk embryogenes

    University essay from SLU/School for Forest Management

    Author : Josefine Björs; Jonathan Sjögren; [2023]
    Keywords : skogsträdsförädling; Picea abies; fröklonförökning;

    Abstract : Gran (Picea abies) har länge varit ett viktigt trädslag för den svenska skogsnäringen. Skogsbruket står inför en oviss framtid och med ett alltmer ostadigt klimat behövs ett genetiskt material som kan klara dessa nya prövningar. READ MORE

  3. 2. Drivers of flower size evolution in the selfing species Arabidopsis thaliana

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Clàudia Fernández Mestre; [2023]
    Keywords : Arabidopsis thaliana; petal size; fitness; selection; evolutionary drivers; GWAS;

    Abstract : The influence of pollinators on the evolution of flower morphology has been extensively explored. Yet, the effect of other ecological factors, such as genetic drift, environmental filtering, and allometric constraints, gained less attention. In this study, we addressed the importance of those drivers in a predominantly selfing species. READ MORE

  4. 3. Sex-associated genomic variation in two ecotypes of Littorina saxatilis on the Swedish west coast

    University essay from Göteborgs universitet/Institutionen för marina vetenskaper

    Author : Amin Ghane; [2022-09-26]
    Keywords : Littorina saxatilis; Sex chromosomes; Sex determination systems; Sex-associated genomic region;

    Abstract : Sex, one of the most conspicuous characteristics of living organisms, has always been fascinating for biologists. The diversity of sex goes much beyond a simple distinction between males and females. Many organisms have more than two mating entities, and many species show some degree of hermaphroditism, at least in part of their life cycle. READ MORE

  5. 4. Genome-wide association studies using machine learning

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Mohammad Mshaleh; [2022]
    Keywords : ;

    Abstract : Genom-Wide Association Study (GWAS) is a field that studies the genomics of organisms. GWAS focuses on what is called single nucleotide polymorphisms (SNP). In GWAS,the data of the SNPs is usually massive, which requires modern statistical analysis methods to investigate the relationship between those SNPs and a phenotype. READ MORE

  6. 5. Genetic mapping on local Swedish chicken breeds

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Samrawit Tsehay Gebeyehu; [2021]
    Keywords : chicken; genetic diversity; GWAS; plumage color; SNP; Swedish chicken breed;

    Abstract : Today, genetic studies are gaining popularity around the world, especially in the developed world. The study of genetic diversity is the basis for genetic protection and future breed improvement. READ MORE
