My sister is a beautiful, gentle kind and polite. She got married to a man of integrity and they were blessed with children. The husband used to provide things for her so as to satisfy the wife. Every week, the husband will take her to the salon by himself and wait till she is through with her hair. The best cloth in town will be seen on my sister even the wife of the governor can not compare herself with her in terms of outfits. She uses latest cars. The husband got a contract that does not give him time with his wife, for about six months. One day, she went out for shopping and met a woman called Sandra. She is also a beautiful woman, they introduce themselves to each other and they started visiting each other as a friend, not knowing to my sister that she will send her out of her marriage. She introduced my sister to some men in her club which led to my sister’s lateness to her house, that is how my sister started clubbing and going out with different men. After some months, my sister got pregnant and delivered a baby. After ten years, my sister’s husband got a contract that should be executed in America. He told his wife and the wife was so happy, because she will have the liberty to operate. The husband will give travel but use to call at least five times in a day to show that his mind is still with her, but my sister had turn to sugar mommy in town. Few months later, the husband returned home and said ’ am home to be with you for three weeks’. I will be back soon but I will be going with my last born so that he can be keeping me company over there. He started processing the visa where he discovered that the child is not his biological child. He got home with anger and ask his wife who is the biological father of the child , the wife said he is the one, the man said it’s better for her to say the truth because the DNA test confirmed that he is not the biological father. My sister started begging that it is her friend that caused it because the husband refuse to give her the attention the wanted. That was what led to the end of their [marriage](https://en.wikipedia.org/wiki/Marriage). ![divoiec.jpg](https://steemitimages.com/DQmboCRm7tcykyC6LadgyKWwFu3mnZduwHDXQcSYjwESWPE/divoiec.jpg) [source](https://pixabay.com/en/breakup-divorce-separation-908714/)

**WHAT IS DNA?**

[DNA](https://commons.wikimedia.org/wiki/File:Eukaryote_DNA-en.svg) is a linear polymer made from recapitulate units called nucleotides. The structure of DNA is active in line with it’s length, being capable of coiling into tight loops and other shapes. In two helical chains, bound to each other by hydrogen bonds. In living organism, DNA does not consistently exist as a single molecule, but instead as a pair of molecule that are held tightly together. These two linear strands entwine like vines. In the shape of a double helix. A genealogical DNA test is a DNA based test look at specific locations of person’s genome in order to find ancestral ethnicity and [genealogical](https://en.oxforddictionaries.com/definition/genealogical) relationships. Result provides information about ethnic groups, the test subject may be descended from and about other individuals that they may be relate to. These are three main types of genealogical DNA test are available with each looking at a different part of the genome and useful for various types of genealogical test.(i) autosomal,(ii) mitochondrial and(iii)Y. Generally, genealogical test does not provide information about medical conditions or diseases. It is a test identify a true son or daughter. ![DNA.png](https://steemitimages.com/DQmcVBShGi7ZKP7NFgQS5bRj3VT5fwVPviQq3QqUA6D65UL/DNA.png) [source](https://commons.wikimedia.org/wiki/File:Eukaryote_DNA-en.svg) ***Watch out for how bioinformatics, BLAST for Basic Local Alignment Search Tool can used for comparing primary biological sequence information, the nucleotides of DNA sequences.... Different types of BLASTs are available according to the query sequences.*** ***Thanks for reading my write up***
