In Drosophila, these genes occur on chromosome 4.
H - wild type (normal) h - hairy
F - wild type f - frizzled
E - wild type e - vestigial
The cross HFE x hfe yielded the following:
Hfe hfe
HFE - 393 HFe - 28
h f e - 409 h f E- 30
H f e - 58 H f E - 1
h F E - 80 h F e - 1
a. (2 pts.) Which group in the progeny represents double cross-overs? Parental types?
b. (1 pt.) What is the correct gene order?
c. (7 pts.) Compute for the distance between genes and draw the linkage map.
d. (2 pts.) Compute for coefficient of coincidence and interference.
