Summary Introduction
To determine:
The argument for or against the strategy. If human activities are contributing to the breeding behavior, determine there is ethical obligation to intervene or not. The polar bears have a better chance of avoiding extinction if humans eliminate their hybrid offspring. Would evidence that polar bears and grizzlies had interbred in the past change.
Concept introduction:
The warm climate on the mainland results in the interbreeding of polar bears with grizzly bears. The humans are the reasons for the warming or increased temperatures in climate.

In the United States, the rare red wolf (Canis lupus) has been known to hybridize with coyotes (Canis latrans), which are much more numerous. Although red wolves and coyotes differ in terms of morphology, DNA, and behavior, genetic evidence suggests that living red wolf individuals are actually hybrids. Red wolves are designated as an endangered species and hence receive legal protection under the Endangered Species Act. Some people think that their endangered status should be withdrawn because the remaining red wolves are hybrids, not members of a "pure" species. Do you agree? Why or why not?
A population of interbreeding birds has been split by a geological event after which the isolated part of the
population started to evolve into an incipient species with different mating rituals. Due to a recent environmental
change the two populations are now able to potentially mate again in what is called a hybrid zone. Mating does
take place every now and then but the hybrid offspring appear less able to survive. As a consequence, mating
rituals start to diverge even further. We call this process of continued divergence?

The red wolf (Canis rufus) was once widespread in the southeastern United States but was declared to be extinct in the wild. Biologists bred captive red wolf individuals and reintroduced them into areas of eastern North Carolina, where they are federally protected as endangered species. The current wild population is estimated to be about 100 individuals. However, a new threat to red wolves has arisen: hybridization with coyotes (Canis latrans), which have become more numerous in the areas inhabited by red wolves. Although red wolves and coyotes differ in morphology and DNA, they are capable of interbreeding and producing fertile offspring. Social behavior is the main reproductive barrier between the species and is more easily overcome when same-species mates are rare. For this reason, some people think that the endangered status of the red wolf should be withdrawn and resources should not be spent to protect what is not a “pure” species. Do you agree? Why or why not?

- The Tibetans and Han Chinese share several genetic traits and DNA. However, the EPAS1 gene, which increases the ability of red blood cells to carry oxygen even in low oxygen environments, is only commonly found in the Tibetan population that live in higher elevations. Explain why this gene is only common in Tibetan populations from the perspective of competitive advantage and natural selection. Write your answer in three to five sentencesarrow_forwardIn one paragraph, using your own words, describe how natural selection led to polar bears evolving to have white fur.arrow_forwardIn a population of pika, you find that individuals vary in their fur color - there are greyish and black pikas. The genetic mechanism behind fur color is mainly regulated by one gene Attractie, and in this population there are only two alleles for the Attractie gene: A1 and A2. Greyish fur color is better camouflaged when they inhabit in talus (broken rocks); black fur helps protect them against predators in coniferous forests, where pika makes burrows under fallen logs and tree stumps. Why might you hypothesize that this pika population is not in Hardy-Weinberg equilibrium? What do you think is happening? Clearly explain your reasoning.arrow_forward

She compared A infection levels for 67 normal males- collected before the flatwing mutation appeared in the population-to 122 flatwing males that she collected after the flatwing mutation appeared. She expected fewer males to be infected by the parasitoid fly after the appearance of the flatwing mutation in the cricket population. Scientific Questions: Why do most male crickets on Kauai have flat wings? Could parasitoid flies have contributed to the loss of song for male crickets? Figure 2: A parasitoid fly, Ormia ochracea, sitting on top of its cricket host, Teleogryllus oceanicus. What is the hypothesis? Find the hypothesis in the text and underline it. A hypothesis is a proposed explanation for an observation, which can then be tested with experimentation or other types of studies.

A population of lizards in Southern California is orange and is poisonous to birds. In central California, where the two species overlap, a new species of non-poisonous, orange lizards arose. Which of the following statements best explains the existence of non-poisonous orange lizards? A) Non-poisonous brown lizards changed color once they noticed birds did not eat orange lizards. B) Non-poisonous orange lizards have a selective advantage since birds avoid orange lizards. C) Non-poisonous lizards turn orange by eating orange flowers and then pass the trait on D) Non-poisonous orange lizards have a selective disadvantage since they cannot blend in. E) Non-poisonous brown lizards are more attractive to mates.arrow_forward
- The approximately 600 species of cichlids in East Africa’s Lake Victoria have largely resulted from sympatric speciation. The closely related cichlids species P. pundamilia and P. nyererei are thought to have arisen by sexual selection. Mate choice by females strongly favors males of their own species that have different body colors. In recent years, pollution has caused the water of Lake Victoria to become turbid in some areas. Hybrids of P. pundamilia and P. nyererei were produced and the gene pools of the two species have started to fuse, creating a new hybrid species. In this process, what are the conditions that led to the fusion of P. pundamilia and P. nyererei? A. Only the prezygotic reproductive barrier is not complete for the two species. B. Only the postzygotic reproductive barrier is not complete for the two species. C. Both the prezygotic and the postzygotic reproductive barriers are complete for the two species. D. Both the prezygotic and the postzygotic reproductive…arrow_forwardThe Chatham Islands are about 850 kilometers off the coast of New Zealand. One species of bird living on the islands, the black robin (Petroica traversi), in 1980 there were only 5 individuals left. Currently, there are already 200 black robins living there: all from a single pair. Using the "fingerprint" method of blood cell DNA, it was proved that all the robins of this species are genetically identical according to the studied gene sequences. They thrive here today. Even 70 percent young survive. And on the continent, only 42% of young Petroica australis survive.. a) i) What can you say about the taxonomic links between the Chatam Islands and the mainland robins in terms of the scientific names of these birds? ii) What could have ever influenced the separation of the two robin populations?arrow_forwardThe Tibetans and Han Chinese share several genetic traits and DNA.

- An adult human has a flat face with a small jaw and large cranium. An adult chimpanzee has a large jaw and small cranium. Both juvenile chimps and humans have heads similar to adult humans. Which of the following is a reasonable explanation for this pattern? Group of answer choices A) genes that modify skull shape are not expressed in chimps during development B) head shape is controlled by cytoplasmic determinants C)genes that modify skull shape are not expressed in humans during development D) chimps and humans have completely different genes controlling the formation of the headarrow_forwardb) () Environment Good Por Corticosterones are often called "stress hormones." Corticosterone concentration in the body can increase when a mammal is experiencing long- term stress, which typically occurs when a mammal lives in a poor environment. The chart above plots the quality of the environment versus corticosterone levels. Two groups of inbred lab mice (C and D) were sampled twice, once in a good environment and once in a poor environment. Provide a possible explanation why members of Group C had higher corticosterone levels in the good environment but members of Group D had higher corticosterone levels in the poor environment. Corticosterone levelsarrow_forwardPolar bears have "white" fur. Identify, with justification, what may have led to the evolution of this trait,arrow_forward
