Individuals of genotype AaBb were mated to individuals of genotype aabb. One thousand off spring were counted, with the following results: 474 Aabb, 480 aaBb, 20 AaBb, and 26 aabb. What type of cross is this? Are these loci linked? What are the two parental classes and the two recombinant classes of off spring? What is the percentage of recombination between these two loci? How many map units apart are they?
