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. When Pooh crossed it with one of his own animals, he obtained plaid tiggers. Interbreeding among the plaid tiggers produced litters of a majority of plaid members, but some crosswise- and lengthwise-striped animals were also produced. Diagram the crosses made Pooh, showing the genotypes of the tiggers which account for the coat patterns observed.
