Explain why blue tits in France were unable to experience local adaptation (i.e., timing reproduction to coincide with peak insect emergence when breeding on holm oaks)? Describe the conditions under which local adaptation to holm oaks could occur?
The crab spider, Thomisus spectabilis, sits on flowers and preys upon visiting honeybees. Do honeybees distinguish between flowers that have crab spiders and flowers that do not? To test this, Heiling et al. (2003) gave 34 bees a choice between 2 flowers: one with, and one without a crab spider. In 24 of the 34 trials, the bees picked the flower that had the spider. In the other trials, the bees chose the spiderless flower.
With these data, carry out the appropriate hypothesis test (one- or two-tailed), using the normal approximation to the binomial distribution to determine Z. For a one-tailed test, use the formula =(1-NORM.DIST(Z,0,1,TRUE) in Excel calculate P. For a two-tailed test, use the formula =2(1-NORM.DIST(Z,0,1,TRUE).
State your answer for the value of P to three decimal places, and include the leading zero.
Do all of the math in Excel
DO NOT round the value of Z.
Substitute the cell (e.g. B1) for Z in the formula for P.

- How is the frequency of cotransduction related to the relative position of genes on a bacteial chromosome? Draw a map of three genes and describe the expected relationship of cotransduction frequencies to the map.arrow_forwardPropose several mechanisms by which animalsmay synchronize the production of offspring with favorableenvironmental conditions.arrow_forwardHoney bees are visiting two food sites, A and B, at 6 AM in the morning, as shown in Fig. 1 and Fig. 2. Bees at site A are collecting pollen; those at site B are collecting nectar. When bees from site A return to the nest, they must find a cell in the wax combs and store the pollen (Fig. 3). Bees from site B pass their nectar to young Receiver Bees when they return to the nest (Fig. 4). 10. True or False: In Fig. 4 the forager that has returned from the field is expressing the forR allele, whereas the younger bee receiving the nectar remains inside the nest and is expressing the forS allele. 11. True or False: In Fig. 4 the forager is expressing the BB genotype at the Gp9 locus, whereas the younger bee inside the nest is expressing the Bb genotype.12. True or False: Compared to the forager in Fig. 4, the younger receiver bee has 2-4 times less activity of the Am-for gene, lower levels of PKG and shows less positive phototaxis.arrow_forward

Bees from site B pass their nectar to young Receiver Bees when they return to the nest (Fig. 4). 7. True or False: Foragers for both sites A and B learn floral color during the 2-3 seconds before they land on the flower, they learn floral order while on the flower, and they learn landmarks while hovering above the flower before flying back to the nest. 8. True or Flase: Site B is closer to the nest than Site A and thus the bees visiting site B are the foragers expressing the forS allele, whereas those visiting site A are the foragers expressing the forR allele. 9.

Bees from site B pass their nectar to young Receiver Bees when they return to the nest (Fig. 4). 16. True or False: In Fig. 4, the forager is passing a pheromone to the young receiver bee that slows the rate of JH increase resulting in the normal progression through the age-based division of labor. 17. True or False: If young bees are prevented from interacting with older bees as shown in Fig. 4, they will have reduced exposure to ethyl oleate, which will result in the upregulation of genes such as Am-for and per, their PKG and PER levels will increase, and they will become precocious foragers. 18.

True or False: The bees in Fig. 4 are engaged in an exchange of liquid food through a process called proctodeal feeding. 15. True or False: During the food exchange shown in Fig. 4, the older forager is passing a pheromone to the younger bee called isopentyl acetate, which upregulates genes associated with nursing behavior and downregulates genes associated with…arrow_forwardHoney bees are visiting two food sites, A and B, at 6 AM in the morning, as shown in Fig. 1 and Fig. 2.

Bees from site B pass their nectar to young Receiver Bees when they return to the nest (Fig. 4). 4. True or False: If foragers are still visiting site B at 10 AM, their waggle runs would be oriented 125 degrees to the right of vertical. 5. True or False: The ability of the foragers to track the passage of time and compensate for the movement of the sun is based on the biological clock located in the deuterocerebrum and involves a 24-hr period of cycling of the genes fem and am-dsx. 6. True or False: The pollen unloading behavior shown in Fig. 3 is a type of associative learning that involves conditioning of the proboscis extension reflex.arrow_forwardExplain the technical differences between a cross-fertilizationexperiment versus a self-fertilization experiment.arrow_forward

True or False: If a sudden storm kills many of the foragers while out in the field, the interactions shown in Fig. 4 will be reduced, which will cause the JH titers of some younger bees to decrease so that they remain nurse bees longer to raise replacement foragers. 20. True or False: In honey bee workers, the per gene and the Am-for gene become active gradually as a bee ages, such that younger bees that remain inside the nest are arrhythmic in their behavior and have lower levels of PKG compared to older foragers.arrow_forward
