1. Question: Whatphenotypes and ratios did you observe in the F1generation?
2. Question: Based onwhat you know about Mendelian genetics, did the F2generation demonstrate the phenotypic ratio that you expected? Ifnot, what phenotypic ratio was obtained with this cross, andwhy?
3. Question:Describe the phenotypes obtained in theF2 generation. Examine the phenotypes and sexes of eachfly. Is there a sex and phenotype combination that is absent orunderrepresented? If so, which one? What does this result tell youabout the sex chromosome location of the white eye allele?(HINT: When analyzing the crossresults, remember that Y-linked traits are passed down only fromaffected males to their sons. Females are unaffected by Y-linkedtraits since they do not have Y chromosomes. On the other hand, both males and females can inheritX-linked traits since they both have X chromosomes.)
