Why are all my dna matches from fathers side

DadвЂ™s contribution makes a big impact and can significantly affect the different traits your little one will have! #2 Y-Linked Traits (for Sons) The Big Picture: All of the physical differences between boys and girls are due to this tiny chromosomal difference. Which means congrats! YouвЂ™re having a baby girl! The X chromosome doesnвЂ™t contain this male-producing gene.The Y chromosome contains the SRY (male-determining) gene, which kickstarts the вЂњvirilizationвЂќ (masculinization) process, including the fetal development of the testes-this means you have a baby boy on the way!.The gendered difference is entirely dependent on this one minuscule genetic distinction: The Supporting Evidence: While mothers will always pass down their X chromosome (considering itвЂ™s the only kind they have), fathers will pass down either an X or Y chromosome at random. What are the physical traits inherited from father? #1 BabyвЂ™s GenderДads are responsible for the gender of their little rugrats, and itвЂ™s one of the physical traits that are 100% contributed by dad. Now that weвЂ™ve covered a brief overview of genetics, letвЂ™s dive into the good stuff. And since fathers are the only ones who can contribute a Y chromosome, Y-linked traits are all thanks to the babyвЂ™s father. Additionally, certain genetic traits are found exclusively on X or Y chromosomes. The presence of a Y chromosome determines whether your babyвЂ™s a boy or a girl. While moms pass down an X chromosome to their children-since women have two x chromosomes-dads pass down either an X or Y chromosome. You may be wondering, вЂњwhere does the hair gene come fromвЂќ or вЂњwhat color eyes will my baby have?вЂќ and we can help narrow the guessing game down for you! But when it comes to tracing certain traits to certain parents, scientists have identified a particular type of gene responsible for parent-specific traits: Sex-Linked Genes A dash of mom, a sprinkle of dad, mix it all together, bake for nine months, and voila: you have a darling little bun, fresh out the oven. Most genetic traits result from a combination of both parentsвЂ™ genetic codes. So whatвЂ™s the truth, and whatвЂ™s an old wivesвЂ™ (or husbandsвЂ™) tale when it comes to traits inherited from the dad? Genetics of Inheritance Maybe your dad is convinced all future children will inherit his love of sports (he may already be stockpiling tiny jerseys). Meanwhile, your best friends keep telling you that your baby girl is going to inherit your killer smile. Maybe your mother-in-law is convinced your daughter is destined for the signature family nose.

A traits DNA test can help remove the guessing game and get you even more excited about your little oneвЂ™s arrival. ItвЂ™s hard not to make guesses and predictions about which traits sheвЂ™ll inherit from you and your partner respectively, and it seems even harder for friends and family not to put in their two cents (or two dollars). It's just not something where you can state 'my family is from such and such country and has always been from such and such country.Speculating about how your future kiddo will turn out can be a fun little game. And with the Roman empire moving all over Europe, you get Middle-Eastern and Northern African migrants too. But Scotland and Romania? I wouldn't make assumptions. I mean if your dad was from Scotland and your mom was from Burma, there's probably not a lot of doubt which side you match someone on.

Third, your ancestors traveled around a lot more than you might think. X recombines less often so aim for segments of at least 10 cM. For regular autosomal, most people only look at segments at least 7 cM. All segments are 'real' but that's not the same thing as 'meaningful.' Anything less than 5 cM is almost always useless. Second, I agree with Leah: disregard segments that are too small.

As others have suggested, look in the chromosome browser. First, make sure these are really X matches.
