As more people have their DNA tested and as the results databases grow, you will have an increasingly better chance of connecting with your birth father by genetic means. While it is true that you are unable to trace your father's identity through his Y-DNA (the traditional male paternity signature) because a female does not inherit it, do not despair: There is another method. Autosomal DNA testing looks at the 22 pairs of chromosomes that do not determine gender. This can be very useful in identifying relationships within five generations of yourself, without being limited to only maternal ancestors.
It is true that your results will be most useful if your biological father or one of his close relatives (preferably his brothers or sisters or his first cousins) also had genetic data registered with the DNA testing company you use. Companies like23andMe (through DNA Relatives) and Family Tree DNA (through Family Finder), as well asAncestry.com and Genographic, can compare the data from these autosomes for shared segments. You should take tests with each of these companies as their databases are proprietary -- that is, they are not shared or overlapping.
The closer the genetic relationship you have with a person in one of these databases, the more identical segments of DNA you will share. And these companies even determine, through the lengths of these segments, if you have a brother or sister in the databases or, indeed, if you descend from a parent. But we stress that this is a very long shot.
According to the 23andMe website, "DNA Relatives uses the length and number of these identical segments to predict the relationship between people." If your birth father himself has contributed his DNA results, you will be able to tell [if] he is your father. A 30 percent to 40 percent match with someone probably indicates that the person is your half-sibling. 23andMe and Family Finder both display predicted relationships between you and the people whose DNA aligns with yours to some degree. This means that by submitting your DNA results, you would be casting a net and hoping that a relative on your father's side has contributed DNA as well. Should you find any such people, you can contact them through the company you have both joined.
Men in your family are like these boats they're anchor pretty close together!
Good morning how are you?
BeantwoordenVerwijderenMy name is Emilio, I am a Spanish boy and I live in a town near to Madrid. I am a very interested person in knowing things so different as the culture, the way of life of the inhabitants of our planet, the fauna, the flora, and the landscapes of all the countries of the world etc. in summary, I am a person that enjoys traveling, learning and respecting people's diversity from all over the world.
I would love to travel and meet in person all the aspects above mentioned, but unfortunately as this is very expensive and my purchasing power is quite small, so I devised a way to travel with the imagination in every corner of our planet. A few years ago I started a collection of used stamps because trough them, you can see pictures about fauna, flora, monuments, landscapes etc. from all the countries. As every day is more and more difficult to get stamps, some years ago I started a new collection in order to get traditional letters addressed to me in which my goal was to get at least 1 letter from each country in the world. This modest goal is feasible to reach in the most part of countries, but unfortunately it’s impossible to achieve in other various territories for several reasons, either because they are countries at war, either because they are countries with extreme poverty or because for whatever reason the postal system is not functioning properly.
For all this I would ask you one small favor:
Would you be so kind as to send me a letter by traditional mail from St Marteen? I understand perfectly that you think that your blog is not the appropriate place to ask this, and even, is very probably that you ignore my letter, but I would call your attention to the difficulty involved in getting a letter from that country, and also I don’t know anyone neither where to write in St Marteen in order to increase my collection. a letter for me is like a little souvenir, like if I have had visited that territory with my imagination and at same time, the arrival of the letters from a country is a sign of peace and normality and an original way to promote a country in the world. My postal address is the following one:
Emilio Fernandez Esteban
Calle Valencia, 39
28903 Getafe (Madrid)
Spain
If you wish, you can visit my blog www.cartasenmibuzon.blogspot.com where you can see the pictures of all the letters that I have received from whole World.
Finally I would like to thank the attention given to this letter, and whether you can help me or not, I send my best wishes for peace, health and happiness for you, your family and all your dear beings.
Yours Sincerely
Emilio Fernandez
