Genes A and B are so close together on the same chromosome that crossing-over occurs between A and B in only 1 in a million meioses. An AA bb individual mates with an aa BB individual to produce an F1 that is A b / a B. If 100 progeny are observed, what genotypic ratio is expected in the gametes produced by the F1
