This model shows the process of natural selection on rabbits demonstrating variation in fur color over several generations. Using the model, what most likely led to the loss of white furred rabbits in the population? A) the white rabbits did not reproduce fast enough to survive B) white was a recessive trait and therefore not passed on to any offspring C) the white fur was a favorable trait but was never prevalent in the population D) the rabbits with white fur had less camouflage in the environment and were more easily preyed on by predators

16 quantitative traits, such as height and weight, that do not fall into discrete categories, are viewed as—————.

What affect will inbreeding tend to have on genotypic frequencies in a population? a) It will increase the frequency of genotypes that produce a dominant phenotype. b) It will decrease the frequency of genotypes that produce a dominant phenotype. c) It will increase the frequency of homozygous genotypes. d) It will increase the frequency of heterozygous genotypes.

1a) In a very large population, if the forward and reverse mutation rates are exactly the same, how would you expect the frequency of an original, non-mutated allele to change in the population over time? Will the population eventually achieve an equilibrium value of the frequency of the non-mutated allele? b) What if the forward mutation rate is one order of magnitude larger (e. 10X) than the reverse mutation rate? Do you expect the frequency of the original, non-mutated allele to increase, decrease, or stay the same over time?  c) If the population size is considerably smaller, does this change your expectations for changes in the frequency of the original, non-mutated allele over several generations?

In the bighorn sheep population of North America, what would happen if all of the large-bodied, large-horned males were hunted, leaving only small-bodied, small-horned sheep?  a)Males could no longer protect females from predators, so eventually all of the sheep would be eaten by predators. b)There would be no phenotypic variation in the population of sheep, and natural selection could not lead to males with larger horns in the future. C)The size of horns would no longer be a heritable traits, and would males would not pass this trait to their offspring. d)Males would begin to use their horns for other behaviors, such as hunting prey or being better competitors.

a) Suppose the frequency of the recessive allele a for the recessive condition albinism is 0.2 Assume the Hardy-Weinberg distribution.    ai) What is the frequency of albinism in the general population?  aii) What fraction of the population are carriers?  b) In a large population of mice, 0.58 have the recessive genetic condition rsiancer (fictional).  Assume the Hardy-Weinberg distribution. What fraction of mice are carriers? Giver your answer with two digits parts the decimal point. c) In a large population of squirrels,  0.14 have the recessive genetic condition nlourianfilindr (fictional).  Assume the Hardy-Weinberg distribution.  What is the frequency of the dominant allele in this population? Give your answer with two digits parts the decimal point. d) In a large population of chimpanzees,  there is a recessive genetic condition telactalase (fictional).  Assume the Hardy-Weinberg distribution.  If the frequency of dominant allele is 0.77 then what fraction of the population has…

Population 2 - Offspring of parent generation above i) What is the blue phenotype frequency? ii) What is the Aa genotype frequency? iii) What is the A allele frequency? c. Is this population evolving? Please explain why or why not. AA AA Aa AA AA Aa Aa Aa Aa Aa Aa Aa aa aa aa aa Aa Aa

Another condition that can occur in squirrel populations is the albino condition. In this condition, squirrels lack all pigmentation resulting in completely white fur and pink eyes. As with leucistic squirrels, albino squirrels are more conspicuous to predators. In addition, the lack of pigment in their eyes results in poor eyesight. These two conditions result in albino squirrels dying off before they reach maturity.   If the lab simulation were to be repeated, but instead of leucism, the recessive condition in the population was albinism, what would you expect to see happen to the allele frequencies for normal pigmentation (G) and albinism (g) over the 10 generations? Remember that no albino (gg) individuals would survive to reproduce in each generation. Would you expect to find g alleles in the population by the 10th generation? Why or why not?

____ refers to the collection of all alleles across all gene loci in a population. a) Genetic drift b) Genotype c) Gene pool d) Gene flow

Considering the Hardy-Weinberg theorem’s assumptions, which of the following statements is NOT correct?  (Recall that there are certain assumptions that must be true in order for the Hardy-Weinberg theorem to accurately predict genotype ratios in the next generation.)a) The population must be very large so there random genetic drift will not occur.b) No natural selection can occur.c) Mating must be random.d) Individuals must migrate into and out of the population so that gene flow will occur.e) Mutations must not occur.
