E.3/16
Vg: normal wings; vg: vestigial wings
Bt: normal wings, bt: bent wings
But to simplify, I write:
V: normal wing; v: vestigial wing
B: normal wings; b: bent wings
P: VvBb x VvBb
Gametes (both) VB, Vb, vB, vb
F1 (Punnett Square)
.....|.... VB...|...Vb...|...vB...|..vb
VB | VVBB | VVBb | VvBB | VvBb
Vb | VVBb .| VVbb | VvBb | Vvbb
vB | VvBB ..| VvBb | vvBB | vvBb
vb | VvBb ..| Vvbb. | vvBb | vvbb
Phenotypic ratio: 9/16 V-B- (normal) : 3/16 V-bb (bent) : 3/16 vvB- (vestigial) : 1/16 vvbb (vestigial-bent)
