30pts this is a biology question. if a mother has a+ blood and a father has a+ blood and the maternal grandparents have a+ blood and the paternal grandparents have unknown blood types, what is the probability of the child having o+ blood ? give percentages for each possible blood type of the child in addition to the initial question.

the chances of having O+ group is 1.5%

I dont think i can give you a percentage on that, but if both parents have A+ blood type, the percentage chance would be pretty low, the thing to expect would be A+, unless one or both of the grandparents have any kind of O blood, the percentage chance would be higher, but even then, A+ has the highest chance

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.
