The 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?

The tiny frog Paedophryne amauensis was discovered by researchers purposefully searching for the source of an unusual sound, but sometimes similarity between two species can lead scientists to accidental discoveries. A previously unknown species of wild cat was inadvertently discovered by researchers who were sequencing the DNA of a house cat–sized South American wild cat called the tigrina. The DNA analysis revealed that many alleles found in the supposed tigrinas living in northeastern Brazil are not shared with other tigrinas. This finding suggested that the northeastern cats do not interbreed with other tigrinas and are therefore a different species. What prevents the two species from interbreeding?
An experiment has been initiated in a laboratory where recombinant DNA technology has been used to substitute the gene responsible for change of colour in chameleon with another gene responsible for “glowin-the-dark”. If this experiment is successful, chameleons carrying the “glow-in-the-dark” gene will not be able to change their colours any longer. Discuss the implication of these results in terms of ethics and conservation biology.
You are studying two populations of pika. You find that the population inhabit in talus (broken rocks) are greyish. Another population live in coniferous forests have black fur. When individuals from each population are brought together in the lab, they produce offspring whose appearance is intermediate between the two parents. The offspring can breed and reproduce successfully with each other or pika of either parent population. You sequence three genes, Pigmentosa, Sparkly, and Zippy. For each of the three genes, the two populations differ from each other at a few nucleotides (<1%). Why is it hard to determine if these two pika populations belong to the same species or are two different species? In your answer/argument, refer to at least two pieces of evidence from the above scenario. Note, we are NOT asking you to determine if these are the same species or not.
Imagine that the volcano on Mt. St. Helens erupts again. All life is removed from the side of the mountain and has to recolonize. Your first task as a geneticist for United States Forest Service is to estimate the frequency of the red allele in the lupine plants that colonize the site. You know that the lupine seeds came from a nearby population where the frequency of the red allele has consistently been approximately 0.2 for many generations. However, in the first year (i.e. first generation, before any local reproduction) on Mt. St. Helens, the red allele of this newly colonized population has a frequency of 0.9. What is the most likely explanation for this difference in allele frequency from the nearby population?
(1) A very large population of birds is living on an island in the Pacific ocean. (2) There are no birds from the same species coming into the island or leaving the island. (3) Each member of the population survives and reproduces at the same rate. (4) When birds are choosing their mates, they choose based on how colorful their feathers are. (5) There are no new mutations arising in the population. Is it likely that this population is in Hardy-Weinberg equilibrium? If not, select the sentence that led you to conclude this. If yes, indicate that below. O Yes, this population is in H-W equilibrium. O Sentence 3 O Sentence 4 Sentence 2 O Sentence 1 O Sentence 5
In the year 2374, humans finally developed the technology necessary for time travel. You are a scientist interested in the population genetics of extinct animals. Taking advantage of this technology advance, you decide to travel back 8 million years to conduct field work in Venezuela. You are studying a population of Phoberomys pattersoni, the world’s largest extinct rodent weighing approximately 700 kg (1500 lbs) and looking vaguely like a giant guinea pig. The coat color of this rodent varies between tan (dominant) and brown (recessive). Assume the population is in Hardy-Weinberg equilibrium. You observed 336 tan Phoberomys and 64 brown Phoberomys during your study. What is the frequency of the homozygous recessive genotype? ________________ What is the allelic frequency of the dominant (tan) allele in the population? ___________ Of the animals you observed, how many were heterozygous? _______________ As you observe the animals you count 200 brown and 450 tan. Conduct a…
Name crickets remain unnoticed by the parasitoid flies. To test this idea, Robin dissected the otS males to look for fly larvae. 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. Scientific Data: Use the data below to answer the scientific questions:…
The delta-32 mutation, a recessive gene, gives humans protection from HIV infection. The allele frequency in a town in Sweden is 20%. What percent of the population have two copies of the gene and are therefore immune to HIV? What percent of the population are less susceptible to the disease since they are heterozygous?
2) The year is 2050. The climate has continued to warm. Areas in northern Canada and Alaska are without snow or ice; the average annual temperature has risen and previously snow-covered areas are now shrub land and some temperate forests. What effect would such a climatic change have on the gene pool of the rabbits? All BUT ONE could apply. In northern Canada, a population of rabbits was predominantly white in color. The allele for white color is recessive (g) while the allele for gray color is dominant (G). Over the last several decades, the average annual temperature of this area has increased and the long-term deposits of ice and snow have become scarce. In this case, the frequency of a previously rare allele becomes more frequent in the population. Choose one.A) The allelic frequency has most likely shifted to 85% GG and 15% gg. B) The dominant allele in the gene pool would become G, the previously rare allele. C) The allele for white, g, would be scarce and perhaps nonexistent…
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?
Your descendants have fortunately inherited your fascination with rodent genetics. Fifty thousand years after the original volcanic eruption, your descendants return to the island where the two populations are still separated. They repeat the same experiments that you carried out. Their data indicate there is no reproductive isolation between members of A1 and A2. DNA sequences from randomly chosen individuals from the two populations are shown here – A1 ATAAGA A1 ACAAGA A1 ACATGA A2 TCATTT A2 TCATTG A2 TCATTT A)Describe relative levels of genetic variation (simply state low or high) among individuals in population A1. B)Describe relative levels of genetic variation (simply state low or high) among individuals in population A2. C)Describe relative levels of genetic variation (simply state low or high) between individuals in populations A1 and individuals in population A2.
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? O Fusion O Behavioral isolation Reinforcement O Postzygotic isolation O Stability
