DNA between siblings are similar if you share the same biological parents. The genetic information you gain comes from both of your parents, and are a result of fertilization of 2 haploid cells fusing to form a zygote that has a diploid number of chromosomes.
The short answer to your question is that both are half siblings. If you and someone else share a dad but not a mom, then you are half-siblings. And if the two of you share a mom but not a dad, same thing.What makes two children full-siblings or half-siblings all boils down to how much genetic information, or DNA, they share.Each of us gets half our DNA from our mom and half from our dad. Full siblings have the same mom and the same dad.So these siblings are getting all of their genetic information from the same two people. Half siblings only share DNA from one parent. The genetic information from the other parent is different.ull siblings have the same mom and the same dad. So these siblings are getting all of their genetic information from the same two people.
