Answer:
P- AA and BB
F1 - AB, AB, AB, AB
F2 - AA, AB, AB, BB
Explanation:
Let the allele for "across strips" be "A"
and the allele for "vertical strips" be "B"
The Genotype of the parents would be
AA and BB
Now in the F1 generation, following offspring will be produced
AA * BB
AB, AB, AB, AB
All the offspring of F1 generation are plaid tigers
In F2 generation, AB is inter crossed with itself i.e
AB * AB
AA, AB, AB, BB
Out of four offspring
One is having across strips - %
One is having vertical strips- %
and two are having Plaid strips - %
