An unaffected woman for a human disorder marries and unaffected man and they have children. This results in 3 affected sons, and one unaffected daughter, which ends up having children later on with an unaffected man and has 2 affected sons. A) Draw a simple pedigree diagram for this family, including a legend. B) What is the likely mode of inheritance of this trait: Please explain C) Provide the genotypes of the original mother and the daughter. Use a capital letter for the dominant allele and lowercase letter for the recessive allele. D) If one of the affected sons from the original marriage marries a 2nd cousin that is a carrier of this trait and has children, what is the probability that they will have 3 affected sons?
