Group of answer choices

Any group of interbreeding individuals capable of producingoffspring under any conditions, including laboratory or clinicalsituations.

A group of organisms that look sufficiently similar to eachother anatomically or genetically.

All organisms that share the same common ancestor.

A group of actually or potentially interbreeding individualscapable of producing reproductively viable offspring under naturalconditions.

All organisms that share a common characteristic that definesthem as a group.

All organisms that inhabit the same habitat, found anywhere inthe world, but it must be natural.

Which of the following statements about Irish wolfhounds(average weight 120 lbs) and teacup chihuahuas (average weight 3lbs) is correct?

Group of answer choices

They look very different and have wildly different sizes, so bythe biological species concept they are different species.

They both look like dogs, so by the biological species conceptthey are the same species.

They look very different and have wildly different sizes, so bythe morphological species concept they are different species.

They cannot physically breed successfully; therefore, by thebiological species concept they are different species.

They look very different and have wildly different sizes, so bythe phylogenetic species concept they are different species.

They both look like dogs, so by the phylogenetic species conceptthey are the same species.

If humans were able to breed them artificially in a laboratoryusing artificial insemination, then by the phylogenetic speciesconcept they would be the same species.

Which of the following statements is (are) correct? Mark allthat apply.

Group of answer choices

Natural selection is a change in allele frequencies; oralternatively, changes in the heritable variation of a populationover time.

Using artificial selection, humans have domesticated around 100different types of wolves; that's why we have some many differentbreeds.

Humans domesticated chihuahuas from a population of tiny wolvesthat looked like chihuahuas from Central America.

Natural selection has only produced one species of canid (dog),namely the wolf.

Using artificial selection, humans have created around 400different breeds of dog from natural populations of wolves.

Natural selection has produced only 4 species of canid (dog),namely wolves, coyotes, foxes and wild African dogs.

Natural selection has produced over 100 species of wild dogs in3 major groups; modern dogs (canids) are only one of thosegroups.

Natural selection is essentially identical to the process bywhich humans created all dog breeds except that instead of breedersdetermining which animals reproduce, nature does.

Most of the genes in modern domestic dogs appear to come from apopulation of wolves in central Asia.

Question 91 pts

The CMAH gene (mark all that apply)

Group of answer choices

produces a protein that allows a particular parasite to invadeorganisms and cause malaria.

is associated with significant increases in blood glucose whenit is nonfunctional in mice.

in humans has a 92 base-pair deletion.

is nonfunctional in all organisms except mice.

in humans is a vestigial trait.

is found only in mice.

in gorillas is nonfunctional.

in humans is much different than in other great apes(chimpanzees, bonobos, gorillas and orangutans), which gives us anadvantage in regions where a certain type of malaria is common.

in humans is a broken version of a functional gene found inother organisms.
