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

An experiment is conducted on the eggs of purple-feathered barn swallows. A clutch of eggs from this nest is separated into two halves. One half of the eggs are left with the purple-feathered parents, and the other half of the eggs are moved to a nest built by gray-feathered barn swallows. Genetic analysis has shown that barn swallows have genes coding for feather color. Upon maturity, all barn swallows left with the original parents have purple feathers, while those that were transplanted have gray feathers. This experiment is repeated with a large number of other nests with similar results. What explains the results of this experiment? A:Color in barn swallows appears to follow a pattern of codominance. B:Genes in the transplant parents appear to influence feather color in barn swallows. C:Genes appear to have no influence on color pattern in barn swallows. D:Color in barn swallows appears to be influenced by both genes and the environment.
An island of the Galápagos archipelago is home to a medium ground finch that subsists mainly by eating seeds. A severe drought struck the island. During the drought, plants produced fewer seeds, and the finches soon depleted the stock of small and soft seeds, leaving only large and hard seeds that were difficult to process. In this environment, finches with deeper beaks were more likely to survive and pass their advantageous traits to their offspring by means of the principle called the 'inheritance of acquired characteristics'. Question 11 options: A) True B) False
In reptiles, sex determination was thought to be controlled by sex-chromosome systems or by temperature-dependent sex determination without an inherited component to sex. But as we discussed in section 7.6, in the Australian lizard, Pogona vitticeps, it was recently revealed that sex is determined by both chromosome composition and by the temperature at which eggs are incubated. What effects might climate change have on temperature- dependent sex determination in this species, and how might this impact the sex ratio for this species in subsequent generations?
Assume you are studying development in two species of iguana. You determine that a certain gene, "SPN2" turns on and off at different times in the two different species. The difference in timing leads to a different body length between the two iguana species. This phenomenon is an example of which of the following terms? a. Punctuated Equilibrium b. Pleiotropy c. Gene duplication d. Heterochrony
An hypothesis for the extinction of the dinosaurs is that the earth had been hit by a gigantic meteor that caused the death of those big reptiles. In that case the entire genetic pool of those animals has been destroyed, invalidating the Hardy-Weinberg equilibrium. In Genetics what is this type of gene frequency change called?
Why are monozygotic twins genetically identical, whereas dizygotic twins share only 50% of their genes on average?a. Monozygotic twins tend to look more similar.b. Monozygotic twins develop from two different eggs fertilized by the same sperm, whereas dizygotic twins develop from two eggs fertilized by two different sperm.c. Monozygotic twins develop from a single egg fertilized by one sperm, whereas dizygotic twins develop from a single egg fertilized by two different sperm.d. Monozygotic twins develop from a single egg fertilized by a single sperm, whereas dizygotic twins develop from two eggs fertilized by two different sperm.
You are raising a stock of Drosophila flies in which you have clipped off the wings of each individual. Assume that this treatment does not disrupt their mating success (it would). If you clip off the wings in each subsequent generation, what would you expect to observe in the 50th generation? Why? This is an example of whose ideas in evolution?
Students in a genetics laboratory began an experiment in an attempt to increase heat tolerance in two strains of Drosophila melanogaster. One strain was trapped from the wild six weeks before the experiment was to begin; the other was obtained from a Drosophila repository at a university laboratory. In which strain would you expect to see the most rapid and extensive response to heat-tolerance selection, and why?
Can ypu answer ALL parts to this question Pigment of chicken feathers is regulated by two genes, the gene for feather pigment C, and a gene that inhibits pigment production, I. A mother chicken, who is heterozygous for gene c, and heterozygous for gene I, is crossed with a father chicken, who is homozygous recessive for the pigment gene, and heterozygous for gene I. Inhibition is dominant to uninhibited, pigmented feathers are dominant to unpigmented feathers. The inhibitor gene (I) will prevent expression of pigmented chicken feathers. Use the letters C, c, I, and i for the genes. C is for color and I is for inhibitor Enter your answer as a list of haplotypes separated by spaces such as AB ab Ab aB. Do not write a sentence. Do not list duplicate haplotypes. Alphabatize your haplotypes, e.g. Ab, not bA. A) What are the potential genotypes of the gametes produced by the mother for these two genes? B) What are the potential genotypes of the gametes produced by the father for…
There are three types of polar bears - ones with thick coats, ones with thin coats, and ones with medium coats. It is fall and soon it will be winter. the temperatures are dropping rapidly and the bears must be kept warm or they will freeze to death. the bears have had an average of 2 cubs each, but due to the extreme temperatures, many mother bears have only one cub left. Darwin's 2nd point is that some variations are favorable. Which of the variations would be favorable in this environment for the population of polar bears?
In a certain population of mice, a single gene controls fur color. There are two possible alleles: B, which leads to a black fur, and W, which leads to white fur. Individuals with the genotype BB will have a black fur, individuals with the genotype WW will have white fur, and individuals with the genotype BW will have gray fur. Scientists recorded the fur color of 1,000 mice from the population. They found that 200 mice have black fur, 400 have gray fur, and 400 have white fur. Ten years later, the measurements are repeated. Again, they recorded the fur color of 1,000 mice. They found that 400 have black fur, 400 have gray fur, and 200 have white fur. Part A: Show the Hardy-Weinberg calculations for the beginning and ending populations. Include the values for the equation as well as the p and q values. Show your work. Part B: Use the Hardy-Weinberg calculation to explain if this population is evolving or not. Then propose a hypothesis about the environment of these mice that would lead…
A male black short furred cat mates with a ginger short furred female cat – without further information and using the information you have provided in your keys above, what are the possible genotypes of these two cats and why? (Hint: You need to show the genotypes as an expression of both genes together - and you need to explain the logic of how you have arrived at your answer). The pair of cats produce in their first litter together the following kittens: 3 tortoiseshell short fur females, 2 tortoiseshell long fur females, 3 ginger short fur males, and 1 ginger long fur male. From this information only (no genetic diagrams required), what evidence can you use to deduce the genetic identity of the parent cats?
