  1. 1. Genetic background of temperament traits in standardbred trotters

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Paulina Berglund; [2021]
    Nyckelord :temperament; standardbred trotter; heritability; low-pass whole genome sequencing;

    Sammanfattning : The genetic background of temperament traits in horses has been subject for research for many years to obtain understanding of domestication, breed differences and welfare. Previous studies have found heritabilities ranging from low to moderate for temperament. LÄS MER

  3. 2. The domestication effects on social support in chickens (Gallus gallus)

    Kandidat-uppsats, Institutionen för fysik, kemi och biologi; Tekniska högskolan

    Författare :Caroline Bergvall; [2012]
    Nyckelord :white leghorn; red junglefowl; social support; acute stressor; unstressed; stressed;

    Sammanfattning : When animals are stressed they use a trait called social support to alleviate their stress responses. With domestication many traits from the ancestor red junglefowl have changed in the domesticated breed white leghorn. White leghorns are bred to be able to live in large groups where it becomes hard to recognize every chicken. LÄS MER

  4. 3. The genetic basis of a domestication trait in the chicken: mapping quantitative trait loci for plumage colour

    Master-uppsats, Biologi; Tekniska högskolan

    Författare :Md. Nazmul Huq; [2012]
    Nyckelord :qtl; quantitative trait loci; genome scan; qtl analysis; plumage colour; domestication trait; chicken; pigmentation trait;

    Sammanfattning : Domestication is the process by which animals become adapted to the environment provided by humans. The process of domestication has let to a number of correlated behavioural, morphological and physiological changes among many domesticated animal species. An example is the changes of plumage colour in the chicken. LÄS MER

  5. 4. Polymorphism in myostatin gene and athletic performance in Nordic horse breeds

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Agnese Viluma; [2012]
    Nyckelord :myostatin; horse; athletic performance; Coldblooded Trotter; Icelandic Horse; Nordic breeds;

    Sammanfattning : Athletic performance including working ability, riding, racing and endurance has played a leading role in horse breeding possibly since their domestication. Even though traits of athletic performance are considered as complex and dependant on environment, management and training, it has been shown that heritability of some performance traits can be considerably high.

  7. 5. Molecular analysis of dog and wolf genomic DNA to explore integration polymorphisms of Canine Endogenous Retroviruses, CfERV

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :MohammadReza Mirzazadeh; [2012]
    Nyckelord :Endogenous Retrovirus ERV ; Canine Endogenous Retrovirus CfERV ; germ line; Vertical transmission; Polymorphism; Copy Number Variation CNV ;

    Sammanfattning : Endogenous retroviruses (ERVs) are found in all examined vertebrate genomes. Different mammals have been reported to contain different amounts of ERVs. For example, in the dog genome 0.15% of sequences are derived from retroviruses. LÄS MER
