Consider three genes on the same chromosome, Gene A, Gene B and Gene C. You perform three factor mapping cross between parentals aaBBCC and AAbbcc, and then cross the F1 triheterozygotes (aABbCc) to a pure breeding homozygous recessive strain (aabbcc). Indicate whether the F2 offspring below resulted from parental or recombinant gametes.

Question
Consider three genes on the same chromosome, Gene A, Gene B and Gene C. You perform three factor mapping cross between parentals aaBBCC and AAbbcc, and then cross the F1 triheterozygotes (aABbCc) to a pure breeding homozygous recessive strain (aabbcc). Indicate whether the F2 offspring below resulted from parental or recombinant gametes.
Expert Solution
Step 1
As 3 genes are located on the same chromosome then the crossing over event is very rare.
