Nothing really. There is no blood relationship between the two.
Yes.
They have the same mother and different fathers.
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.
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.
Individuals who share the same mother but have different fathers are known as half-siblings. They are related through their mother but only share one biological parent.
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.
it makes sense
They are half siblings.
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.
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.
It is possible for two siblings to have different biological fathers, a situation known as heteropaternal superfecundation. This can occur when a woman ovulates multiple eggs and has intercourse with different partners within a short timeframe. In this case, while rare, it is possible for both sisters to have the same mother but different fathers. Confirmation through DNA testing can provide definitive answers.
