half.
They have the same mother and different fathers.
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.
They are half siblings.
Yes.
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.
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.
Yes, because they the same mother - but different fathers. So they have different last names.
In most cases, your sister's mother is also your mother, and her husband is your father. If you and your baby sister have the same father but different mothers, your sister's mother's father is your father. If you and you sister have the same mother but different fathers, your baby sister's father is your step-father if he is married to your mother.
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.
Yes, if you have the same mother but different fathers, you are considered half-sisters. This means you share one biological parent, which creates a familial bond, even though you have different fathers. The term "real sisters" can vary in meaning, but in terms of biological relationship, you are indeed sisters.
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:)
