Blood types in humans are caused by a combination of two of three possible alleles - IA, IB, and i. The i allele is recessive and individuals homozygous for this allele have blood types O.  Blood type A may be due to either homozygous condition or the IA i   Blood type AB is caused by having a copy of both the IA and IB alleles.  Rh factor is another “marker” on human red blood cells and is either positive (dominant—RR or Rr) or negative (recessive—rr). Franks has blood type A-negative. Frank’s father is B-positive and his mother is AB-positive. Frank marries Susan, a woman that is B-positive.  Susan’s mother is A-negative and her father is AB-positive.  Give the genotype of all of the individuals mentioned above.   b. Give the genotypes and phenotypes of the possible offspring from this marriage
