In humans, three alleles affect blood type. The A and B alleles are codominant, and the O allele is recessive. An AB blood type father has children with an A blood type mother (genotype AO).
What are the chances that their children will have AB type blood?

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."

the answer is 100% density i've answered this question before and done the quiz myself.
