the sims could live in hogwarts and interact with other students and go to classes and shit and instead of the skills being athletic, logic, gardening etc it could be potions, charms, transfiguration, etc
she says the baby’s blood type is O+ and that the mother is A (we’ll assume - since she didn’t specify but did for +) and so therefore the victim couldn’t be the baby’s mother because the baby’s genetic mother couldn’t be A.
blood typing is one of the few genetic markers that isn’t influenced by multiple different genome locations causing variations in the expression of the genes (think shades of skin tones or eye color- it’s not as simple as ‘white skin’ or ‘blue eyes’). blood type is affected by 1 chromosomal location on 2 chromosomes with one donated from each parents. a second location determines the rH factor (aka + or -)
the genes are governed this way; A is dominant, B is dominant, and O is recessive. a person with A blood type could either have A/A (with both genes expressing A) or be A/O (with A dominating the O meaning it’s only expressed as A). because both A and B are dominant when a person is A/B both genes are expressed equally and the person is considered AB blood type. O is the lack of a dominant gene and the only way to get O is to have two recessive genes. the rH factor is easier- if you have one or more + then you’re a plus, if you have no + then you’re -.
so the victim is blood type A. she could be A/O and if the father is an O carrier also (meaning he can be A/O, O/O, or B/O) then she would have at least a 25% chance of having an O/O baby. (possibilites with B/O are A/B, B/O, A/O, and O/O) (possibilities with A/O are A/O, A/O, A/A, and O/O) (possibilities with O/O are A/O, A/O, O/O, O/O).
basically, the only way they can rule the mother out without knowing the father’s blood type this early in the game is if the baby were AB and the mother was O or vice versa. they are the only incompatible blood types.
That awkward moment when you realize that this gif, which everyone uses to show their love of Harry Potter, is actually a scene in which Voldemort's supporters attack Hogwarts.
Speaking of… there are a shit ton more Death Eaters than I thought. And all the Light had was more or less a bunch of students? It’s a freaking miracle they aren’t all living under the Dark Lord’s reign.
