Consider a population of birds with three color morphs, each with a different genotype. red birds leave 10 offspring in the next generation, orange birds leave 8 offspring, and yellow birds leave 2 offspring. based on this information, indicate whether the following statements are true or false.

a. the relative fitness of red birds is 0.5.
b. the relative fitness of yellow birds is 0.2.
c. the difference in fitness between red and orange birds is 0.1.
d. the difference in fitness between orange birds and yellow birds is 0.6.
e. natural selection would favor red birds over yellow birds.

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.

Give two examples of what would occur if one of the pairs did not match or had an extra chromosomes. explain how this might occur, and if it would be dangerous to the individual. fast.
