Some of the same but not completly, they would have some from the parent they share but not the other one.
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 inherit your DNA from both of your biological parents. Half of your DNA comes from your mother, and the other half comes from your father. This genetic material combines to determine your unique characteristics and traits.
A person can have a DNA test done to see if someone is their half brother. The DNA would have to be taken from both half brothers and both parents or the parent they both believe is their biological parent.
The sisters could be the result of two separate sets of identical twins who married each other and had children. This would mean that genetically, the sisters are siblings, but due to the unique combination of DNA from both sets of twins, they appear very similar in appearance and age.
It is only half of what DNA would look like
You have no blood line relation, You don't share DNA whatsoever. In this scenario putting an example; you and your half-sister share, let's say, the same father but not the same mother and your half-sister's half-sister share the same mother but not the same father. There is no shared DNA between you and your half-sister's half-sister.
no, not quite. a child gets it's genetic material from it's parents. half from the mother and half from the father. when reproductive cells divide the gametes(like sperm and eggs) that result are not exact copies each time either. when they are being produced in the body there is a factor or randomness that makes each gamete a little different. so sisters both get half their DNA from their mother and half from their father but it's not necessicarily the same half. so sisters have similar genetics but not the same. on the other hand mothers and daughters share some ofthe exact DNA, not all of it but some. so your DNA is more like your mothers than your sisters, unless you're an identical twin, then your the same amount of related to your sister and your mom!
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.
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.
It is very unlikely that two brothers would have babies with the same DNA. That could only happen if identical twin brothers married identical twin sisters, and even then the mixing of DNA during reproduction makes this an extremely unlikely outcome.
You share approximately 50% of your DNA with each of your biological parents. This is because you inherit half of your DNA from your mother and half from your father during the process of genetic inheritance.
you have to give the DNA sequence formula for ex: TCGAACT the other half must be AGCTTGA
You inherit your DNA from both of your biological parents. Half of your DNA comes from your mother, and the other half comes from your father. This genetic material combines to determine your unique characteristics and traits.
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.
If you have a sister with the same dad but different mom, then she's probably your half-sister, although she would have about 25% of the same DNA as yours.
Not based on real research but only logic and reason it is unlikely that cousins would have identical saliva. They may be similar, but they do have different DNA and different genetics. Each person is unique. It would be as if you said that they are the exact same person.
A person can have a DNA test done to see if someone is their half brother. The DNA would have to be taken from both half brothers and both parents or the parent they both believe is their biological parent.
