Using the link provided. Mate two flies. a male is a wild type and a female has yellow body and purple eyes. Use: https://www.sciencecourseware.org/FlyLabJS/ Which mutant alleles are dominant? Which mutant alleles are recessive? Which mutant alleles are sex-linked? Which mutant alleles are autosomal? Can you tell at this point if the two genes are linked? Show the results of the dihybrid analysis. Are genes segregating independently? What is the evidence for or against this? Show the crosses you will use to obtain the mapping data. For the mapping crosses, Write out the crossing scheme and make a table of the results (ignore sex in this table, combine the male and female progeny). Identify the parental classes and the recombinant classes. For a 3-point cross, identify the double cross overs. Show your calculations for the recombination frequencies between the three genes (for the 3-point cross) or the two genes (for the two-point crosses). Draw a map of the Drosophila chromosomes 2, 3, and X, including your genes and all of the known mapping genes. Discuss the role of each unknown gene in their respective pigmentation pathway. Describe why the loss of the gene resulted in the mutant colored eye or fly body. Do estimated map positions map the reported positions reported in flybase?
