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.

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
