• B. Wing size
• C. Eye colour
• D. Wing colour

Answer 1

Answer: (A), (B), (C)

The correct options are
A Body colour
B Wing size
C Eye colour

He crossed fruit flies having three (linked) genes (for wing size, eye color and body colour) on the same chromosome and noticed that the recombination frequency differed considerably from the Mendelian principles of independent assortment.
