[q json=”true” yy=”4″ unit=”7.Evolution_and_Natural_Selection” dataset_id=”Unit 7 Population Genetics FC Dataset|1c82cbea6dfadc” question_number=”1″ topic=”7.1-3.Natural_and_Artificial_Selection”] Explain Darwin’s theory of natural selection.

[a] Natural selection explains the phenomenon of design (adaptation) without a designer. The theory begins with two observations. First, in any population, there’s inherited variation. Second, in every species, even the ones with the lowest rate of reproduction, parents produce more offspring than will survive into the next generation.

Among the offspring, some will possess inherited advantages that increase their chances of surviving and reproducing. As a result, individuals with those advantages will survive at a higher rate. When they reproduce, they’ll pass on their inherited adaptations to their offspring. As mutation continues to randomly generate new variations, and as the environment removes less adapted individuals from a population and allows better-adapted individuals to survive to reproduce, that population, generation by generation, continually adapts to its environment.

[a] In any population, most characteristics can be represented by a bell curve of continuous variation. For example, if you’re measuring body length, most individuals will be of average length, with fewer that are shorter, and fewer that are longer. Directional selection (A) selects against one of the extremes. Stabilizing selection (B) selects against both extremes. Disruptive selection (C) selects against the mean.

[a] Evolutionary fitness is measured by reproductive success: the number of offspring (and offspring of offspring) that survive to reproduce.

[q json=”true” yy=”4″ unit=”7.Evolution_and_Natural_Selection” dataset_id=”Unit 7 Population Genetics FC Dataset|1c828ab9210adc” question_number=”4″ topic=”7.1-3.Natural_and_Artificial_Selection”] Explain how the peppered moth demonstrates evolutionary change in response to environmental change.

[a] The Peppered Moth (Biston betularia) provides an example of directly observed directional selection. Before the industrial revolution in England in the 1800s, the moth’s predominant phenotype was peppered: mostly white, with black specks. This camouflaged the moths against bird predation as they rested on light-colored tree trunks which were often covered by whitish-colored lichens. Soot from industrial pollution killed the lichens and darkened the tree trunks, creating an advantage for darker moths. Starting in the mid-1800s, over several decades, the mean phenotype shifted from peppered to dark. Starting in about 1960, soot from pollution declined. The lichens returned, and the tree trunks became lighter. In response, the mean phenotype of peppered moth populations shifted from dark-colored to light-colored.

[q json=”true” yy=”4″ unit=”7.Evolution_and_Natural_Selection” dataset_id=”Unit 7 Population Genetics FC Dataset|1c827cc0d9b2dc” question_number=”5″ topic=”7.4-5.Population_Genetics_and_Hardy-Weinberg”] Explain evolution in terms of genes and gene pools.

[a] In terms of genes, evolution can be explained as the change in the genetic makeup of a population over time. This change can be adaptive, resulting from natural selection of phenotypes associated with specific alleles. Through natural selection, alleles that code for traits that increase evolutionary fitness (the ability of organisms with these alleles to survive and reproduce) will increase in frequency within a gene pool, while alleles that decrease fitness will decrease in frequency. However, changes in a population’s genetic makeup can also be random, resulting from processes such as genetic drift (discussed in other cards).

[q json=”true” yy=”4″ unit=”7.Evolution_and_Natural_Selection” dataset_id=”Unit 7 Population Genetics FC Dataset|1c826c748676dc” question_number=”6″ topic=”7.4-5.Population_Genetics_and_Hardy-Weinberg”] Define genetic drift, and describe how a population bottleneck works.

[a] Genetic drift is a random change in allele frequencies in a population”s gene pool, usually associated with a small population size. In a population bottleneck, some biotic or abiotic factor wipes out a large percentage of the individuals in a population, leaving only a few survivors. Because of the small number of individuals left, it’s possible that the alleles they possess might not be representative of the allele frequencies in the former (larger) population. That includes the possibility that some alleles might completely disappear. Note that the survivors didn’t have any selective advantage: they were merely lucky. The overall effect is that allele frequencies in the new surviving population might be quite different from those in the previous population.

[q json=”true” yy=”4″ unit=”7.Evolution_and_Natural_Selection” dataset_id=”Unit 7 Population Genetics FC Dataset|1c825c28333adc” question_number=”7″ topic=”7.4-5.Population_Genetics_and_Hardy-Weinberg”] Describe the founder effect.

[a] If during an emigration event, a small number of individuals from a larger population found a new population, then the allele frequencies in the founders might be different from those in the parent population. As a result, allele frequencies in the newly founded population might wind up being different from the frequencies in the parent population. This is called the founder effect, and it’s another example of genetic drift.

[q json=”true” yy=”4″ unit=”7.Evolution_and_Natural_Selection” dataset_id=”Unit 7 Population Genetics FC Dataset|1c824e2febe2dc” question_number=”8″ topic=”7.4-5.Population_Genetics_and_Hardy-Weinberg”] Explain the effect of gene flow on evolving gene pools.

[a] Gene flow is the movement of alleles from one population to another. This can involve the movement of individuals, who bring their alleles with them from one population to another, or the movement of gametes (such as pollen flying in the wind or being carried by pollinators between adjacent plant populations). In either case, the effect of gene flow is to diminish differentiation between adjacent populations.

[q json=”true” yy=”4″ unit=”7.Evolution_and_Natural_Selection” dataset_id=”Unit 7 Population Genetics FC Dataset|1c82393b80dedc” question_number=”9″ topic=”7.4-5.Population_Genetics_and_Hardy-Weinberg”] Explain the importance of mutation in evolution.

[a] Mutation is the ultimate source of genetic variation within and between populations. Active mutations are the basis of the phenotypic variation upon which natural selection acts.

[q json=”true” yy=”4″ unit=”7.Evolution_and_Natural_Selection” dataset_id=”Unit 7 Population Genetics FC Dataset|1c82269b21bedc” question_number=”10″ topic=”7.4-5.Population_Genetics_and_Hardy-Weinberg”] What is the Hardy-Weinberg principle? In your response, include the five features of a population that”s in Hardy-Weinberg equilibrium.

[a] The Hardy-Weinberg principle describes an idealized, non-evolving population. This population has 5 features, and if any of these are not adhered to, allele frequencies in that population will change.

These features are 1)  infinitely large population (preventing genetic drift); 2) no harmful or beneficial alleles (preventing natural selection); 3) random mating (preventing sexual selection); 4) no emigration or immigration (preventing gene flow) and 5) no net mutation of one allele into another (which would decrease the frequency of the former allele and increase the frequency of the latter).

[q json=”true” yy=”5″ unit=”7.Evolution_and_Natural_Selection” question_number=”11″ dataset_id=”Unit 7 Population Genetics FC Dataset|1c820f52aad6dc” topic=”7.4-5.Population_Genetics_and_Hardy-Weinberg”] Describe the meaning of the Hardy Weinberg equation p + q = 1.

[a] In the Hardy-Weinberg equations, p = the frequency of the dominant allele and q = the frequency of the recessive allele.  The first Hardy Weinberg equation is p + q = 1, which means that for a particular gene locus with only two alleles, the frequency of the dominant allele plus the frequency of the recessive allele equals 100% of the alleles at that locus. Using that equation, if you know the frequency of either the dominant or the recessive allele, you can figure out the other one.

[q json=”true” yy=”5″ unit=”7.Evolution_and_Natural_Selection” question_number=”12″ dataset_id=”Unit 7 Population Genetics FC Dataset|1c81eeba045edc” topic=”7.4-5.Population_Genetics_and_Hardy-Weinberg”]

  1. Describe the meaning of the Hardy Weinberg equation p2 + 2pq + q2 = 1.
  2. Explain what this equation enables you to figure out about a population”s genetic structure.

[a] The equation,  p2 + 2pq + q2 = 1,  means that the frequency of homozygous dominant individuals (p2), plus the frequency of heterozygotes (2pq), plus the frequency of all the recessive individuals (q2) = all the individuals in the population. Once you know the frequency of recessives (which you can identify by phenotype), then you can figure out the frequency of q (it’s the square root of the frequency of recessives). Then you can figure out the frequency of the dominant allele (1-q= p), and then the frequency of heterozygotes (2pq).

[q json=”true” yy=”4″ dataset_id=”Unit 7 Population Genetics FC Dataset|1c8159b70b5edc” question_number=”13″ unit=”7.Evolution_and_Natural_Selection” topic=”7.4-5.Population_Genetics_and_Hardy-Weinberg”] Sickle cell disease is caused by a recessive allele in the gene for hemoglobin. It can significantly decrease quality of life and lifespan. Yet the allele is in high frequency in certain populations. Explain.

[a] Sickle cell disease occurs only in children born with two copies of the recessive allele that codes for a defective form of hemoglobin. Heterozygotes, with only one mutated version of the hemoglobin gene, can experience a small amount of sickling, but not enough to generate the pain crises and tissue damage experienced by homozygotes. However, the change in hemoglobin chemistry creates a hostile environment for the Plasmodium parasite that causes malaria. The result is that heterozygotes have resistance to malaria, resulting in natural selection that has increased the frequency of the sickling allele in populations that live in malaria-prone areas. This phenomenon is called heterozygote advantage, and it can explain the high frequency of an allele that is harmful in homozygotes.
