  1. 1. Analysis of relatedness and genetic diversity in Swedish sheep breeds using medium density (50K) SNP data

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

    Author : Krishani Devika Wijesinghe Sinhalage; [2023]
    Keywords : sheep; genetic diversity; population structure; inbreeding; runs of homozygosity; coat colour; MC1R;

    Abstract : The local Swedish sheep breeds belong to a group of sheep breeds known as North European short-tailed sheep breeds. Evaluation of genetic diversity, relatedness, and population structure of local breeds offers crucial metrics to prevent inbreeding depression, genetic erosion, and crossbreeding between locally adapted and exotic sheep breeds since these occurrences can have detrimental effects and ultimately lead to extinction.

    Abstract : Management of wildlife and husbandry of captive animals have in common the fact that they rely on a solid base of knowledge about the concerned species in order to be successful. The management of the European bison represents an encouraging story of conservation and captive breeding managing to bring a species back from the brink of extinction to a relatively safe status in the wild.
