The flea beetle (P. nemorum) can survive on multiple types of plants, including radishes, eggplants and tomatoes. There is a dominant gene allele that allows P. nemorum to live on Bittercress (B. vulgaris). Radishes, eggplants and tomatoes all have some phenotypes that resist damage by P. nemorum and thus survive better. There are many different biological scenarios that can be modeled by PopG with the above information. Select alternative hypothesis that can be modeled by a one locus, two allele program like PopG. Select one or more: A resistant-flea beetle allele in radishes will change its allele frequency in the presence of the flea beetle (P. nemorum). Tomatoes and radishes will grow better without the flea beetle in the environment. The B allele allowing flea beetle (P. nemorum) growth on Bittercress, will become change its frequency in an environment with predominant Bittercress.

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:…
Wild-type strains of the haploid fungus Neurospora canmake their own tryptophan. An abnormal allele td renders the fungus incapable of making its own tryptophan.An individual of genotype td grows only when its medium supplies tryptophan. The allele su assorts independently of td; its only known effect is to suppress the tdphenotype. Therefore, strains carrying both td and su donot require tryptophan for growth.a. If a td ; su strain is crossed with a genotypically wildtype strain, what genotypes are expected in the progenyand in what proportions?b. What will be the ratio of tryptophan-dependent totryptophan-independent progeny in the cross of part a?
The gene for pea pod colour has two alleles. The dominant allele, G, is associated with the dominant trait of green pea pod colour. The recessive allele, g, is associated with the recessive trait of yellow pea pod colour. For many years, there has been a large collection of pea plants with a mixture of yellow and green pea pod colours in a savannah. But there has been a recent infestation of wild rabbits with a preference for eating plants with yellow pea pods. Assume that at the start of the infestation, the alleles in the pea plant population were in Hardy-Weinberg equilibrium. (a) What does it mean for the alleles in the pea plant population to be in Hardy-Weinberg equilibrium? (b) What is expected to happen to the allele frequency of the g allele in the subsequent pea generations after the rabbits have been introduced? Explain your answer using terms from Darwinian evolution.
Anthocyanin is a pigment that gives flowers and leaves purple colors. The M gene codes for a transcription factor (Myb) that promotes expression of an enzyme that produces anthocyanin. The W gene codes for a different enzyme (Chs) that allows anthocyanin to be deposited in plant leaves and flowers. The dominant phenotype is the production of functional Myb and Chs. 1) Plants that have the mm genotype do not show any purple color. What is the best explanation for why this is? a) Anthocyanin cannot be deposited into the flowers and leaves b) Anthocyanin is not produced in the plant cells c) The M gene is codominant to the W gene d) The M gene is epistatic to the W gene 2)Assume a plant has the genotype MMww. Would this plant have any purple flowers? a) Yes b) No
Malaria is a leading cause of human illness and mortality worldwide, with 200 million people infected and 600,000 deaths each year. In the 1960s, the incidence of malaria was reduced owing to the use of insecticides that killed mosquitoes in the genus Anopheles, which transmit the disease from person to person. But today, mosquitoes are becoming resistant to insecticides--causing a resurgence in malaria. In this exercise, you will investigate whether alleles encoding resistance to insecticides have been transferred between closely related species of Anopheles. To find out whether transfers have occurred, you will analyze DNA results from two species of mosquitoes that transmit malaria (Anopheles gambiae and A. coluzzii) and from A. gambiae × A. coluzzii hybrids. Resistance to DDT and other insecticides in Anopheles is affected by a sodium channel gene, kdr. The allele r of this gene confers resistance, while the wild type (+/+) genotype is not resistant. Researchers sequenced the kdr…
One problem with this line of criticism is that it is difficult to distinguish good forms of manipulating nature from unacceptable ones. Some critics of GMOs argue that we ought to leave species as we find them, and that it is the cross-species transfers of genetic material involved in some GMOs that make them unacceptable. One problem with this objection is that similar transfers have occurred in nature—from basic plant genetics to the long-term patterns of evolution. Please explain what does it mean
Feather color in parakeets is produced by the blending of pigments produced from two biosynthetic pathways shown below. Four independently assorting genes (AA, BB, CC, and DD) produce enzymes that catalyze separate steps of the pathways. For the questions below, use an uppercase letter to indicate a dominant allele producing full enzymatic activity and a lowercase letter to indicate a recessive allele producing no functional enzyme. Feather colors produced by mixing pigments are green (yellow + blue) and purple (red + blue). Red, yellow, and blue feathers result from production of one colored pigment, and white results from absence of pigment production. What is the genotype of a pure-breeding purple parakeet strain? Express your answer as combination of allelic symbols. Example: AaBBccDd.
In the species Polyfarius obscescens, one gene controls lipid storage. Individuals with the dominant F allele are fat, and individuals homozygous for the f allele are not. Transgenic individuals that contain the GFP gene (which produces green fluorescent protein) have also been created. A geneticist has mated a P0 generation green and fat individual with another individual that is neither green nor fat. Using appropriate genetic nomenclature, list all of the possible genotypes of both parents.
Suppose that you are studying the role of Protein B, which you believe plays a role in regulating PCD/Apoptosis in mice. You create two lines of mutant mice. One (bb) is homozygous for a loss-of-function allele of gene B. The other (Bb) is heterozygous, with one wild-type allele and one loss-of function allele. Initially you pay particular attention to two phenotypes of the resulting mice:(i) The morphology of their paws (see picture)(ii) The size of their brains & shape of their skulls. The bb mice have unusually large brains and unusual protrusions from their skulls. Suggest one other aspect of mouse morphology or physiology that you might expect to be altered in the absence of Protein B. Briefly explain your reasoning. Also, based on the apparent effect of Protein B on the likelihood of PCD/Apoptosis, would you classify Protein B as the product of a proto-oncogene or of a tumor suppressor gene?
In the fish Species a, the expression of different combinations of four Hox genes results in structural differences in tissues and organs along the anterior-posterior axis. Figure 3 shows the expression pattern of four genes, i.e. Genes 1 – 4, and the tissue produced along the embryonic anterior - posterior plane of fish Species a wild type. The influence of Hox genes on the formation of specific types of tissue can be determined by introducing gain-of-function and loss-of-function mutations in specific Hox genes. Looking at Figure 3, predict what would happen to each one of the four types of tissues, if the expression of gene 3 was expanded anteriorly by a gain-of-function mutation so that the pattern of gene 3 expression would be the same as that of gene 2.
When the F1 bees were backcrossed to the inbred resistant line produced 4 types of offspring in equal numbers: ¼ if the back-cross offspring showed the complete hygienic behavior pattern ¼ of the back-cross offspring showed none of the elements of hygienic behavior ¼ of the back-cross offspring would uncap the cells of the diseased larvae but these workers would not remove the diseased larvae ¼ of the back-cross offspring would remove the diseased larvae (once the experimenter had uncapped the cells of the diseased larvae) Is it possible that two gene loci are involved in the resistant behavior? Justify your answer.
