4) Pooh had a colony of tiggers whose stripes went across the body. His American pen-pal Yogi sent him a tigger whose stripes ran lengthwise along its body. When Pooh crossed it with one of his animals, he got plaid tiggers in the F1 generation. Interbreeding of the plaid tiggers produced litters of 50% plaid, 25% vertically striped and 25% horizontally striped animals. State the genotypes of the P, F1, and F2 generations. Explain the results.

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 - [tex]\frac{1}{4} * 100 = 25[/tex] %

One is having vertical strips- [tex]\frac{1}{4} * 100 = 25[/tex] %

and two are having Plaid strips - [tex]\frac{2}{4} * 100 = 50[/tex] %
