Unless they're an identical twin, no... or at least, it's EXTREMELY unlikely. If you're female, your DNA should be 50% similar to a sister; if your sibling is of the opposite sex, your DNA will average slightly less than 50% similar (a fraction of roughly 22/46); and if you're male, your DNA will average slightly more than 50% similar to a brother (24/46) because the Y chromosome is inherited exclusively through the father.
What else can I help you with?
Why do siblings look alike?
because siblings share much of the same DNA. if the parents are the same, then each child will have half it's DNA for either parent, so siblings will share an average of half their DNA, ending up with the similar characteristics that their DNA codes for. for siblings with only one parent in common, an average of a quarter of their DNA is the same.
Do half siblings share the same DNA?
No, half siblings do not share the same DNA. They share only one biological parent, so they have some genetic similarities but also differences in their DNA.
Is your mother or father's DNA strand transcribed?
Both your mother's and father's DNA strands are transcribed to produce messenger RNA (mRNA) during gene expression. This mRNA is then translated into proteins that carry out various functions in the body.
Is it possible that DNA of siblings born from same parents totally do not match at all?
Such an event is highly impossible because siblings receive the same set of genes from their parents. The slight differences in their DNA is due to allelic differences and due to recombinational events. However, no such event can cause a total mismatch of the DNA of two siblings from the same parents.
How do you know if you and your siblings have the same parents?
Try a DNA test with a doctor present.
Do DNA of the siblings born from the same parents match?
DNA of siblings are not complete matches of each other but show some similarity and common banding patterns. In case of identical twins, however, the DNA is a perfect match.
True or false Millions of individuals have identical DNA profiles?
False. No one, except identical siblings, have the exact same DNA profiles.
What are the genetic implications for siblings who share the same father but have different mothers in terms of their DNA?
Siblings who share the same father but have different mothers will have different DNA because they inherit genetic material from both parents. This means they will have different genetic traits and characteristics, even though they share a common father.
Can full siblings share 25 of their DNA?
Yes, full siblings typically share about 50 of their DNA, which means they can share up to 25 of their DNA from each parent.
Who would you share more DNA with brother or son?
You share more DNA with your son because you pass on half of your DNA to your child, while siblings share, on average, half of their DNA, but it can vary due to genetic recombination.
You can prove siblings are related by?
similarities in the DNA
How does having the same mother and different fathers make you a whole sibling verses have the same father and different mother Doesn't the dna of the father determine that?
I believe that if you have the same dad then you are not half bro/sis. I believe that it is the dna of the father that determines biological siblings. I have five children with my husband and three of them have different mothers and I tell them all the time that they are NOT step anything or half anything because they all have the same dad. That's my story and I am sticking to it unless the world of medicine proves me wrong:)
