Please help me with these answers to this biology problem, I want to know if they are correct?

Question

Fill out two Punnett squares for a cross between a make with blood type B and a female with Blood type AB. (it is unknown if the father is genotype BB or BO from the information given. So there are two solutions to the possible cross). The calculations and probabilities should be in terms of the phenotypes (blood types) not the genotypes.

1. What are the possible blood types for the cross between the type B (BB or Bo?) make and AB female? The possible blood types would be AB, BB, B or O

2. What are the percentages or probabilities for each blood type in the offspring? The percentages would be BB:2 (50 percent), BO:2 (50 percent), AB:2(50 percent), BB:2 (50 percent), O (25 percent),

3. What blood type(s) would not be possible in a cross between these two parents? Blood type A would not be possible between these two parents.

Are these the correct answers...?

Help me please...

Answer 1

1) the possibles are AB, BB, AO, BO

thats because    AB + BB = AB, AB, BB, BB (Punnett square 1)

and AB + BO = AB, BB, AO AND BO (punnett square 2)



for questions 2 and 3....you can use the answer for question 1 to answer the other questions.  

also make sure you answer in phenotypes not genotypes.  What that means is you need to write "Type B" not BB.

If you need more help, lemmie know! :)
