What pattern of inheritance does this trait follow? 1 15 7 8 9 10

Assume that a particular unusual phenotype is caused by an autosomal recessive allele. John marries Jane, and they have a daughter Mia together who has the unusual phenotype. John has a brother Carlos who appears normal. Jane has a sister Margit with the unusual phenotype. John and Jane are not related, and none of their parents have the unusual phenotype. Draw a 3-generation pedigree that depicts the entire scenario and assign the most likely genotypes to each individual. (You can use any letter you wish to represent the gene.) Yes, you should include Jane's parents and sister, and also John's parents and brother, as part of the pedigree. And don't forget Mia!
