Other traits far more prevalent among people of Celtic ancestry include lactase persistence and red hair, with 46% of Irish and at least 36% of Highland Scots being carriers of red-head variants of the MC1R gene, possibly an adaptation to the cloudy weather of the areas where they live. Although they are not usually considered a Celtic nation, the Faroe Islands have a population with a large Celtic heritage in genetic terms. Recent DNA analyses have revealed that Y chromosomes, tracing male descent, are 87% Scandinavian, whereas the mitochondrial DNA, tracing female descent, is 84% Celtic. The same can be said about Icelanders. The founder population of Iceland came from Ireland, Scotland, and Scandinavia: studies of mitochondrial DNA and Y-chromosomes indicate that 62% of Icelanders' matrilineal ancestry derives from Scotland and Ireland (with most of the rest being from Scandinavia), while 75% of their patrilineal ancestry derives from Scandinavia (with most of the rest being from the Irish and British Isles). In addition, there are some areas of the accepted Celtic countries whose population are mostly not of Celtic heritage: for example, the Orkney and Shetland Islands in Scotland have populations of mostly Nordic descent. Migration from Celtic countries A significant portion of the populations of the United States, Canada, Australia and New Zealand is composed of people whose ancestors were from one of the "Celtic nations". This concerns the Irish diaspora most significantly (see also Irish American), but to a lesser extent also the Welsh diaspora and the Cornish diaspora. There are three areas outside Europe with communities of Celtic language speakers: the province of Chubut in Patagonia with Welsh-speaking Welsh Argentines (known as Y Wladfa) Cape Breton Island in Nova Scotia with Scottish Gaelic-speaking Scottish Canadians southeast Newfoundland with Irish-speaking Irish Canadians. The most common mother-tongue amongst the Fathers of Confederation which saw the formation of Canada was Gaelic. There is a movement in Cape Breton for a separate province in Canada, as espoused by the Cape Breton Labour Party and others. In some former British colonies, or particular regions within them, the term Anglo-Celtic has emerged as a descriptor of an ethnic grouping. In particular, Anglo-Celtic Australian is a term comprising about 80% of the population. Music The claim that distinctly
