- How much genotypic variation do you find in the randomly picked parents of your crosses?Individuals of genotype AaBb were mated to individuals of genotype aabb. One thousand offspring were counted, with the following results: 474 Aabb, 480 aaBb, 20 AaBb, and 26 aabb. What type of cross is it? Are these loci linked? What are the two parental classes and the two recombinant classes of offspring? What is the percentage of recombination between these two loci? How many map units apart are they?In which type of cross(es) can we apply and demonstrate the law of segregation and law of independent assortment? Why can’t we apply the 2 Mendelian laws on monohybrid crosses? Explain briefly. How can one use a pedigree chart to hypothesize how a certain condition is transmitted? Can a pedigree chart show probability of occurrence more accurately than the Punnett square? Why or why not?
