12. (12pts) I want to do a 3 point mapping experiment in Drosophila. The three genes are autosomal, and the traits are all homozygous recessive. My three genes are: Sonic hedgehog (sh) Cactus (ca) Mummy (mu) A female fly is heterozygous for all three traits, and she is crossed with a male that is homozygous recessive for all three traits. Please use sh*, cat, and mut to represent wildtype dominant alleles, and sh, ca, and mu to represent mutant recessive alleles. If there were no double crossover phenotypes observed, please determine the arrangement of alleles (including correct order) in the female parent using the following results of the cross. Number Observed 80 42 Phenotypes Wildtype Sonic hedgehog Sonic hedgehog, mummy Sonic hedgehog, cactus, mummy Cactus Cactus, mummy 384 70 386 38 Chromosome: Chromosome: b) What is the distance between sh and ca?
