Part 5: Linkage Groups When two alleles are located on the same chromosome they are inherited together. However, crossing-over can occur during meiosis and the alleles are switched. Vestigial wings (VG) and Black body color (BL) are located on chromosome 2. mn bielasarner.com 7. Cross a female VG, BL fly with a wild-type male. (ggbb x GGBB). What is the genotype and phenotype of the offspring? 8. Choose a female from the offspring and mate it with a male that has vestigial wings and a black body (ggbb). Show a punnett square or a visual representation of the alleles involved in this cross to make a prediction about the offspring. 9. Complete the table (ignore sex). Phenotype Observed Proportion + (wild-type) Vestigial wings (B.gg) Black body (bbG.) VG, BL (ggbb) 10. How does crossing-over affect the observed outcomes? Explain why the observed flies do not match your prediction. 11. The percentage of crossing over events is used to develop a map of chromosomes. View the chromosome map on the last page. How far apart are the alleles for black body and vestigial wings? (Do the math!) 12. View the proportion of flies from your data that indicate crossover occurred (VG and BL flies) and multiple it by 100. Based on your data, how far apart are these alleles?
