Wild x Apterous Sepia - Dihybridism crossing #5

Interchromosomal recombination Chr II and Chr III.
Mutations studied: absence of wings and sepia eyes.

Presented in a Petri dish, in a perfectly transparent resin, the fruit flies are easily observable under a magnifying glass and maintain the realistic "lab-like" character of fruit fly counts.
Parents, F1, F2, and back cross are available in individual boxes of 40 individuals sorted and counted. The proportions of flies in each box correspond to the expected theoretical frequencies.

Parents box = 20 fruit flies of each parent P1 and P2.
F1 box = cross between P1 and P2.
F2 box = cross between F1 and F1.
Back cross (BC) box = cross between F1 and recessive parent.
