So i just went online to finish up what i thought was my last assignment and just found this assignment i somehow looked over and it is due tonight at 12 am! I am terrible at Punnet Squares so if anybody could help me it would be greatly appreciated!!!



Use a Punnet square to figure out the following crosses:



1) A male with blood type A mates with a female with blood type B. What are the possible genotypes for the parents and the children? What are the phenotypes?



2) A male with blood type AB mates with a female with blood type A. What are the possible genotypes for the parents and the children? What are the phenotypes?



3) A male with blood type AB mates with a female with blood type O. What are the possible genotypes for the parents and the children? What are the phenotypes?
