Answer:
F1) 100% wild type, Pr Vg / pr vg
-----Pr--------Vg------
-----pr---------vg------
Explanation:
<u>Available data</u>:
- Two genes located on the same chromosome
- red eyes (Pr _) are dominant to purple eyes (prpr)
- normal wings (Vg _) are dominant to vestigial wings (vgvg)
Cross: A pure breeding red-eyed fly and vestigial wings with a pure-breeding purple-eyed fly and normal wings
Parentals) Pr vg / Pr vg x pr Vg / pr Vg
Gametes) ----Pr-------vg---- ----pr-------Vg----
----Pr-------vg---- ----pr--------Vg----
F1) 100% wild type, Pr Vg / pr vg
-----Pr--------Vg------
-----pr---------vg------
