1. 1. Genetics of gaits in Icelandic horses

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

   Författare :Johanna Axling; [2015]
   Nyckelord :gaits; SNP; EBV; tölt;

   Sammanfattning : A genome-wide association analysis of Icelandic horses has shown that a mutation in DMRT3, doublesex and mab-3 related transcription factor 3 (‘gait keeper’ mutation), has a strong impact on gait pattern. The DMRT3 mutant allele (A) has been found in high frequency in gaited breeds, and breeds used for harness racing, while non-gaited breeds were homozygous for the wild-type allele (C). LÄS MER

3. 2. Effects of a mutation on the TSHR gene on social and fear related behaviours in chickens.

   Master-uppsats, Institutionen för fysik, kemi och biologi

   Författare :Johanna Axling; [2011]
   Nyckelord :Dometrication; Thyroid hormone; Chicken; Fearful behaviour; Dominant behaviour; Thyroid stimulating hormone receptor TSHR .;

   Sammanfattning : It has been shown that thyroid hormones are important in development and growth in birds and further that thyrotropin (TSH) signaling regulated photoinduced seasonal reproduction. In addition to controlling the development of certain physiological traits, TSH can affect a wide range of phenotypes related to domestication such as behaviour, growth rate, more frequent reproductive cycle’s, pigmentation and also behaviour.
