7. (2.5pts) What larval stage should be used for the hermaphrodite in a cross? Why is it important not to use an adult hermaphrodite when setting up a cross? Extra Credit (10pts): Use the parental crosses described in question 4. If the F1 progeny produced from adding a true- breeding bli-1 L4 hermaphrodite and a true-breeding wildtype adult male are transferred to a plate are allowed to breed, what genotypic ratios would you expect in the F2 generation? What phenotypic ratio would you expect if the bli-1 allele acts as a dominant allele? What phenotypic ratio would you expect if the bli-1 allele acts as a recessive allele? How would the F2 genotypic ratio and phenotypic ratio be different if the true-breeding bli-1 L4 hermaphrodite undergoes self-fertilization instead of cross fertilization and these F1 progeny reproduce?Explanation / Answer
