F1 hybrid from cross T and U is = TU ( toxin resistant duse to presence of antidots)
in First case- F1 male is XO
F1 hermaphrodite is XTU & OTU (because hermaphrodite animal has both male and female gametes)
X | O | |
XTU | XXTU | XOTU |
O | XO | OO |
50% progeny will die due to lack of T strain
In case of 2- T male (XT, OT) and F1 hermaphodite
XT | OT | |
XT/XT | XXTT | XOTT |
XO | XXOT | XOOT |
0% progeny die in this case because all progeny has T strain
In case 3- F1 male ( XT, OT ) and U hermaphodite
XT | OT | |
XU | XXTU | XOTU |
OU | XOTU | OOTU |
25% progeny will die because F1 male restore the T starin with antidote.
