The aim of this study is to investigate genetic variants and gene interactions, which play a role in the development of curly hair. In our previous analyses we were able to detect specific mutations for curly hair. Expression analyses revealed that there are interactions of different genes involved in the determination of tightness and thickness of curls. Due to these findings, we are going to use Mangaliza pigs as an animal model for the horse to investigate these interactions that affect seasonal and temperature-dependent modifications of curly hair. The sampling is going to take place in a uniform environment, in monthly intervals and in F1 and F2 generations of Mangaliza x German Large White or German Lanrace matings. Due to the short generation interval and high number of progeny, the pig is an appropriate model and thus enables a new approach for research of hair development. In addition, the identification of a genetic variant responsible for the Mangaliza breed-specific phenotype contributes to species conservation of this endangered breed.

这项研究的目的是调查在卷发发育中发挥作用的遗传变异和基因相互作用。在我们之前的分析中，我们能够检测到卷发的特定突变。表达分析表明，不同基因之间存在相互作用，涉及卷发的松紧度和厚度的确定。由于这些发现，我们将使用曼加利萨猪作为马的动物模型来研究这些影响卷发随季节和温度变化而变化的相互作用。采样将在统一的环境中、每月一次、在 Mangaliza x 德国大白马或德国 Lanrace 交配的 F1 和 F2 代中进行。由于猪的世代间隔短、后代数量多，是一个合适的模型，从而为毛发发育的研究提供了新的途径。此外，对导致 Mangaliza 品种特定表型的遗传变异的鉴定有助于该濒危品种的物种保护。
