Can twins have the same mom but different dad. and vise versa?

They may share the same mother but different fathers (in which case they are known as uterine siblings or maternal half-brothers/half-sisters), or they may have the same father but different mothers (in which case, they are known as agnate siblings or paternal half-brothers/half-sisters.

My teacher was in one when she was in high school. these abusive lovers can ruin you. mentally and physically. my teacher got a black eye once. she wasn’t able to attend parties or even her moms birthday party all because her bday wanted her to himself.
