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 stripped and 25% horizontially striped animals.
state the genotypes of the p f1 and f2 generations.
