Welsh translation of 'Sense about genetic ancestry testing' ahead of S4C documentary

26 February 2015

Our popular guide to genetic ancestry testing is now available in Welsh.

'Sense about genetic ancestry testing', our guide to commercial genetic tests that companies claim can tell you about your personal history, has been translated into Welsh. We published the original English guide in 2013.

The translation comes ahead of a new television series, DNA Cymru, on the Welsh-language channel S4C. The series is part of a project that uses commercial genetic ancestry tests to answer "who the Welsh are" and which famous historical figures they are related to.

But as the guide explains, these tests are "little more than genetic astrology", using histories so general as to be personally meaningless. Scientists have warned that everyone's tests could be used to show a relation to any famous person or historical group of people, such as the Celts or the Vikings.

If you want to find out how to use DNA tests effectively as part of your family history research, see Debbie Kennett's blog.

Mae ein canllaw poblogaidd sy'n helpu pobl i wneud synnwyr o brofion llinach genetig masnachol wedi ei gyfieithu i Gymraeg. Fe gyhoeddon ni'r ddogfen Saesneg wreiddiol yn 2013.

Daw'r cyfieithiad fel mae S4C yn paratoi at lansio'u rhaglen newydd, DNA Cymru, ar Ddydd Gwyl Dewi. Mae'r rhaglen yn rhan o brosiect sy'n defnyddio profion llinach genetig masnachol i geisio ateb "pwy yw'r Cymry." Mae'r rhaglen hefyd yn edrych ar hanes genetig nifer o wynebau adnabyddus, gan gynnwys y canwr Dafydd Iwan a'r cyn-chwaraewr rygbi Gareth Edwards.

Ond fel mae'r canllaw yn dangos, dyw'r profion hyn "fawr gwell na sêr-ddewiniaeth enetig," yn defnyddio hanesion sydd mor gyffredinol nes eu bod nhw'n ddiystyr. Mae gwyddonwyr wedi rhybuddio fod y gellid defnyddio canlyniadau pawb i ddangos yr un perthnasau â phobl enwog neu grwpiau fel y Celtiaid neu'r Llychlynwyr.

Os hoffech chi gael mwy o wybodaeth am sut gallwch ddefnyddio profion DNA yn effeithiol fel rhan o ymchwil i'ch hanes teuluol, darllennwch flog Debbie Kennett.
