it makes sense
Yes.
They have the same mother and different fathers.
Nothing really. There is no blood relationship between the two.
A half-brother (or half-sister) is one with whom you share only one parent, i.e. you have the same mother but different fathers or the same father but different mothers.
Sid is Tom Sawyer's half brother because they share one parent in common - their mother. They have different fathers, which makes them half siblings.
A maternal brother refers to a man's brother who is the son of the same mother. In other words, both individuals share the same mother but have different fathers, making them half-brothers. This term emphasizes the maternal side of the family relationship.
Because the children have the same mother but different fathers, they are half-siblings (half brothers or half sisters, depending on their sex). But because their different fathers are brothers, they are also first cousins, and each child's father is uncle to the other child. Both relationships apply at the same time, but it is usually easier to use the closest of the possible relationships, so they will usually be thought of as half-siblings.
Not full brother and sister, but in sharing the same blood line ofthe mother, you are considered to be related by half of the parentage, in this case, on the mother's side. Whether one becomes full brother/sister is a matter of love,compassion, acceptance, and the half factor becomes a matter only of legality. You are half brother and sister. You share your mothers blood but not your fathers.
A stepsister is one where there are no blood ties, only related by marriage. If you are both a natural child of one of the parents then it would make you half sisters. Same mother, different fathers. Same father, different mothers.
Your half-brothers and half-sisters (half-siblings) are called half because instead of having the same mother and the same father as you, you have only one parent in common. Thus, you have half the common parentage that full siblings have. Half-siblings have the same father and different mothers, or the saem mother and different fathers.
If you have the same mother but different fathers, you are considered half-siblings. This means you share 50% of your genetic material from your mother. Full siblings, on the other hand, share both parents, resulting in a closer genetic relationship. In summary, having the same mother and different fathers makes you half-siblings.
