If a homologous pair of chromosomes fail to separate during meiosis i, what will be the result?
a) 2 gametes will have 2 of these chromosome and 2 will have 0 of these chromosomes.
b) none of the gametes will have the affected chromosomes.
c) 2 gametes will be normal, 1 gamete will have 2 of the affected chromosomes and 1 gamete will have 0 of the affected chromosomes.
d) 2 gametes will be normal and gametes will have 2 of the affected chromosomes.

What is a universal way that predation benefits the predator? predation increases mate availability. predation in defense of space. the predator gets the energy it needs to survive. the predator keeps parasites from hurting the species.

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.
