Step by step
Solved in 2 steps
- Explain why the following statement is false: Sexual reproduction is the only mechanism for genetic change.Each of the vertebrate Hox genes is present in 4 copies of the genome (TRUE or FALSE)"CG islands are thought to have arisen during evolution because they were associated with portions of the genome that remained unmethylated in the germ line" is true or false.
- Whether the statement "In the small intestine, stem cells in the crypts divide asymmetrically to maintain the population of cells that make up the villi; after each division, one daughter remains a stem cell and the other begins to divide rapidly to produce differentiated progeny" is true or false.The image above shows that, with respect to the WRN gene, the individual with Werner syndrome (WRN) is: Choice 1 of 2: Heterozygous Choice 2 of 2: HomozygousSuppose that the probability of survival of the three different types of diploid individuals in mosquitoes, as a result of the drug, is given by the constants WRR, WRS, and WSS. What are the frequencies of the three different types after this differential survival?
- A farmer mates normal pigs and 38 offspring are born. Of these, 29 are normal, and 9 have swollen forelegs and die soon after birth. Explain the genetic basis for this.The diagram below represents results of agarose gel electrophoresis performed after PCR amplification of a molecular marker in diploid organisms. Answer the following questions: a) How many individuals are homozygous and how many are heterozygous? b) How many alleles are there in this population?Chapter 1 considered the theory of the inheritance of acquired characteristics and noted that this theory is no longer accepted. Is the central dogma consistent with the theory of the inheritance of acquired characteristics? Why or why not?
- Sickle-cell disease is an autosomal recessive disorder that causes the red blood cells of an affected person to be rigid and abnormally shaped. The life expectancy of a person affected by the disorder is approximately 45 years. Carriers of the disease produce some sickled cells, but not enough to be symptomatic.Malaria is a potentially fatal disease caused by the protist Plasmodium falciparum.Studies have shown that those affected by sickle-cell disease (genotype ss), as well as carriers who possess only one sickle-cell allele (Ss), are much more resistant to malaria than those with homozygous dominant genotypes (SS). This resistance is created in part by the rupturing of any sickled red blood cells that are infected with the parasite, preventing Plasmodium falciparum from reproducing and making it more susceptible to the host's immune system.Which of the following statements best predicts what would happen in response to a prolonged epidemic of malaria in a population with no previous…The GMO salmon, Aqua Advantage, will not be able to successfully reproduce with salmon of the wild because they are triploid. What genetic principle can explain thisHaving identified the genetic identity of the parent flies female is RrGg and male is Rrgg. (R is dominant trait for red eyes and r is the recessive trait for brown eyes. G is the dominant trait for Grey body and g is recessive trait for yellow body) fully proof your answer to show thesimultaneous transmission of the two genes involved to give rise to the progeny (57 red-eyed females with grey bodies, 61 red-eyed females with yellow bodies, 22 brown-eyed females with grey bodies, 20 brown-eyed females with yellow bodies.59 red-eyed males with grey bodies, 63 red-eyed males with yellow bodies, 20 brown-eyedmales with grey bodies, 18 brown-eyed males with yellow bodies) with the use of genetic diagrams and summaries as required. (Hint: you are only requiredto show the simultaneous transmission from the P to F1 generations)
