pls answer only item no. 7, 8, and 9. thank u in advancee!
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.

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).

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?
