Question

1. Hermione Granger, in her role in the Ministry of Magic, has decided to settle once and for all the genetics of muggle-borns vs witches and wizards. Using data from her own extended family, along with consulting Hogwarts: A History, she has identified two loci that are involved in this question, M and S.  

Her genotype she has identified her genotype as mm SS, whereas her parents (muggles) are both MmSs and Mmss. Harry Potter is also mmSs, whereas Ron is mmSS. She even managed to steal some DNA from Mr. Filch (a squib—or non magical child of a witch and a wizard), and found his genotype is mmss. Based on this information, what can you conclude about the M and S loci?
