How do you answer these questions? i have attached them on a document. is the answer 1, 2, or 3 and why? 
There are 2 questions

undergoes meiosis. What are the possible genotypes for the daughter 
cells produced? For each genotype, determine the probability that this particular 
genotype can be inherited (assume no crossing over has taken place).

1. AB, Ab, aB, ab each with 25% probability
2. AB, Ab, aB each with 33% probability
3. AB, ab each with 50% probability
b. The diploid cell below has the following genotype with respect to gne A and B: 
AaBb. Both gene A and B are located on different chromosomes. Assume that 
this cell undergoes meiosis. What are the possible genotypes for the daughter 
cells produced at the end of meiosis? For each genotype, determine the 
probability that this particular genotype can be inherited. Assume no crossing 
over has taken place.

1. AB, Ab, aB, ab each with 25% probability
2. AB, Ab, aB each with 33% probability
3. AB, ab each with 50% probability
