do siblings have the same genetic ethnicity?

Because of recombination, siblings only share about 50 percent of the same DNA, on average, Dennis says. So while biological siblings have the same family tree, their genetic code might be different in at least one of the areas looked at in a given test. That's true even for fraternal twins.

Yes, cousins share about 25% of their DNA (siblings, such as your mother and her brother, share ~50%). So any such DNA testing should show this relationship. ... It would mean that either of you is not the biological child of their parent (mother, uncle), OR that the siblings are not biological siblings.

Your parents and their siblings are all in the same generation, and the parents of their spouses are in the same generation as your parents. Your children and any children your siblings have will be the same generation. ... Your 1st-cousins are the children of your aunts and uncles.

If your parents don't have it but a brother or sister does, you have about 5% chance of getting type 1. That's about the same as if your father had it. If your identical twin has it, though, your odds may be as high as 50%.

Yes there is genetic variation and some younger siblings may be taller than the first, but the majority are not as tall as the first born. There can be many reasons for this, but most likely it is the health and nutritional status of the mother declines and depletes with every pregnancy.

Because with the division of DNA, each identical twin may be offered with different genes that can influence a lot of physical features. So, it is not something to worry about if you have twins who look the same but have different skin colors or hair quality, or eye color or anything like that, it is quite normal.

On rare instances you might find a half-sibling here. Your AncestryDNA close family matches could include an aunt or an uncle, a niece or a nephew, a great-grandparent or a great-grandchild, a half-sibling, or a double-first cousin.

And since brothers and sisters can have different blood types, so too can fraternal twins. ... Identical twins come from the same egg and the same sperm and so share nearly identical DNA. For identical twins to have different blood types, something needs to happen to one twin's DNA.

Twins that appear to be of different races could result from heteropaternal superfecundation, as described here. DZ twins, like other siblings, share on average half of their genes. ... By chance, the children of mixed race parents could inherit many more of the genes typical of one race than the other race.

They are 'technically' related. It is several generations apart (over a couple hundred years). But technically everyone is related to everyone in this world. So there is also that.

Handwriting of the siblings within a family resembles the influence of their parents writing, hence, it can be assumed that the handwriting of the siblings will also resemble from each other. ... Due to this their writing style, it is quite possible that the writing characteristics may be found similar with each other.

Ancestry Composition DNA clearly shows connections among those who consider themselves to be Ashkenazi Jewish: two Ashkenazi Jewish people are very likely to be "genetic cousins," sharing long stretches of identical DNA.

Like you, your siblings inherited 23 chromosomes from each of your parents. But because of DNA swapping, their chromosomes have a different combination of genes than yours. Yet on average, half of the genes are still the same.
1355455
Siblings are usually more alike because the detail of the activity of the cells is like the closest source, the same parents, but this is often not the case. ... My siblings and I had similar voices, but I think that my parents resembled each other a lot (even though they were born in different places).

It's possible, but unlikely for the skin colors of twins to be very different. Identical twins have to have the same skin color, because they have the exact same genes, they started out as one embryo that split into two. ... From her mother, she gets all genes for white skin.

No it doesn't. Neither of your parents has to have the same blood type as you. For example if one of your parents was AB+ and the other was O+, they could only have A and B kids. In other words, most likely none of their kids would share either parent's blood type.
597906
After all, kids get their genes from the same parents. But brothers and sisters don't look exactly alike because everyone (including parents) actually has two copies of most of their genes. ... Parents pass one of their two copies of each of their genes to their kids. Which copy a child gets is totally random.
