Melanin is a skin pigmentation that absorbs and dissipates broadband UV rays. Since UV radiation causes DNA damage, melanin pigments protect the skin and reduce the risk of cancer. When skin is exposed to sunlight, melanin production is increased, causing the skin to tan. This demonstrates that Select one: a. the environment causes mutations that have no effect on the chance of survival b. the expression of some genes is influenced by the environment c. the environment causes mutations that increase the chance of survival d. the environment causes mutations that have a large effect on the chance of survival

If this model continues, with no major changes to the environment, what do you expect to happen? A) rabbits will continue to get lighter over time B) there is no way to predict because mutations are random C) mutations will all die out leaving only the original fur color D) dark gray fur will become the common phenotype because it favors survival

Why is it easier to manipulate embryonic stem cells to differentiate into various tissues than it is to manipulate a typical adult cell? a. As cells develop, signaling pathways can cause some genes to be turned off during development. b. Adult cells have different DNA content than do embryonic stem cells. c. Emybronic stem cells pose less of a threat for organ rejection as do an individual s own adult cells. d. It is no easier to manipulate emybronic stem cells to differentiate into various tissues than it is to manipulate a typical adult cell.

Which of the following statements regarding loss of function and gain of function mutations is true? A. If both gain of function and loss of function approaches show the consistent results it is the most convincing evidence to demonstrate the function of gene B. Gain of function mute tapes are the most of case recessive C. Gain of function approach is more convincing than loss of function approach D. Over expression of a gene cannot be considered as gain of function

Hox genes are activated in specific regions of the body (e.g. back of the head) and activate other genes to build specific structures in those regions. This was largely discovered by looking at the effects of mutants of the various hox genes. What other technique would provide information on the action of hox genes? Group of answer choices A. copy hox genes and place them in bacteria B. copy hox genes and place them in plants C. completely remove all hox genes from the genome D. change the control of hox genes so that they are expressed in different body regions E. reverse the order of the hox genes on the chromosome
What is NOT an example of antagonistic pleiotropy? A. Developmental genes that code for greater or fewer than seven cervical vertebrae have negative fitness costs. B. Genes that create insect breathing tubes cause decreased production of growth hormones. C. Mutations that confer resistance to Bt also make insects more vulnerable to natural plant defensive chemicals. D. Two of the three choices are correct.
For a mutation that does not have a fitness cost to the individuals who carry it, we call the mutation a -synonymous mutation -beneficial mutation -dominant mutation -homologous mutation -neutral mutation
Another mutation has occurred in the Andean condor, which is further endangering the survival of the species: Frizzled feathers. This trait results from a mutation in the a-keratin gene, and this mutation causes the feathers to curl. If two frizzled condors happen to mate, rather than producing offspring with frizzled feathers, one observes that 25% of the condor chicks have normal (straight) feathers; 50% have frizzled (curly) feathers, and an unfortunate 25% have “over-frizzled” feathers, which are extremely brittle and resemble pipe cleaners. Birds having this “over-frizzle” trait have great difficulty flying. When a condor that is homozygous for the normal feather allele is mated with one of these “over-frizzled” birds, all of the chicks will have frizzled feathers. Please NAME and EXPLAIN the genetic phenomenon described here.
Some mutations result in proteins that function well at onetemperature but are nonfunctional at a different (usuallyhigher) temperature. Siamese cats have such a “temperaturesensitive” mutation in a gene encoding an enzyme that makesdark pigment in the fur. The mutation results in the breed’sdistinctive point markings and lighter body color (see thephoto). Using this information and what you learned in thechapter, explain the pattern of the cat’s fur pigmentation
