You become interested in monarch butterfly conservation and begin investigating milkweeds (genus Asclepias), their larval host plant. You decide to construct a phylogeny for Illinois milkweed species based on DNA sequence data. You sequence a chloroplast gene from five species, as shown in the table below. For your outgroup, you sequence Tropical milkweed, a species that is more distantly related to the other species. Using parsimony, construct the tree that requires the fewest number of mutations. Starting with your inferred ancestral sequence, mark each mutation and its sequence position on your tree. Hints: Assume the outgroup sequence is the ancestral sequence. Focus on the shared mutations (synapomorphies). Sites that do not vary among species are not useful for phylogenetics and can be ignored. Mutations that only occur in one species (autapomorphies) should be marked on the tree but do not help in constructing the tree. Table 1. Sequence 175-186 in chloroplast trnL/F gene…
According to "Homo naledi – New Questions on Human Evolution ", where was Homo naledi found and how many individuals were found there? A.South Africa and 2 individuals B.Kenya and 2 individuals C.South Africa and 15 individuals D.Kenya and 15 individuals
Which of the following alleles is most likely to increase in a population due to natural selection? A. An allele that prevents peptidoglycan synthesis B. An allele that causes a helminth to produce eggs more quickly C. An allele that creates a non-functional cytoskeleton D. An allele that prevents algae from capturing blue light in photosynthesis
According to "Our Earliest Ancestors", why can’t scientists just do DNA analysis on these fossil hominins to determine if they are a separate species and possibly what species they belong to? A.The fossils would need to be in a -5 degree Celsius environment to prevent DNA from degrading B.The DNA of fossil hominins is too similar to modern humans, making it difficult to distinguish between them. C.Scientists can't perform DNA analysis on fossil hominins because the fossils have been contaminated with modern human DNA over the years, making it impossible to isolate the ancient genetic material. D.The technology for extracting DNA from fossils hasn't been developed yet
What is the most likely evolutionary advantage of sexual reproduction? a. Sexual reproduction is more efficient than asexual reproduction b. Sexual production minimizes adverse mutations c. Sexual reproduction is associated with faster recombination. d. Sexual reproduction leads to significant genetic recombination. e. Sexual recombination is associated with more numerous offspring Which of the following is unnecessary for adaptation? a. Replication b. Selection C. Time d. Competition e. Variation
Why did Galton modify the quincunx? a.Because the distribution of a trait (e.g., height) in offspring is more widespread than that of their parents. b.Because the distribution of a trait (e.g., height) in offspring remains constant relative to that of their parents. c.Because the distribution of a trait (e.g., height) in offspring has a higher mean relative to that of their parents. d.Because the distribution of a trait (e.g., height) in offspring is less widespread than that of their parents.
Which of the following statements about molecular markersare true?A. All molecular markers are segments of DNA that carryspecific genes.B.

We can follow the transmission of a molecular marker byanalyzing the phenotype (i.e., the physical characteristics)of offspring.D. We can follow the transmission of molecular markers usingmolecular techniques such as gel electrophoresis.E. An STS is a molecular marker.

A. maternal rather than Mendelian inheritance pattern is observed B. a specific genetic mutation is observed C. the ATP production is affected D. a rare parasitic disease is associated with this disorder
Segmental duplications play an important role in evolution by a. giving rise to new genes and multigene families. b. keeping the number of genes in a genome constant. c. eliminating repetitive sequences produced by transposition. d. controlling the base content of the genome.
Some species undergo polyploidy, which is a multiplication of their chromosomes. That is, they contain full chromosomes from each parent. How could speciation affect a polyploid organism? A. The polyploid organisms may experience gametic isolation. B. The polyploid organisms may experience behavioral isolation. C. The polyploid organisms may experience geographic isolation. D. The polyploid organisms would not be affected by speciation.
