Nerodia sipedon insularum is a species of the Northern Water Snake that lives on islands in the western part of Lake Erie. This snake exhibits polymorphism (many color forms) and can be described as Banded (BB), intermediate (Bb) and unbanded (bb).  The mainland populations of this snake are all banded.  The islands have sandy shores which the snakes reside compared to rocky shores of the mainland.  In 1980-1984, Richard King conducted a study of mark recapture to look at the numbers of each of these morphs of snakes and for the Island of Pelee this was the population size:  Banded:  71 individuals; Intermediate:  80 individuals; Unbanded 20 individuals.  Give the genotypic frequencies for each morph and then give the allele frequencies for this population.

A population of fuzzy-wumpkins differ in how fuzzy their fur is. Populations in cold climates are fuzzier than in warm climates. Fuzzy-wumpkins mate for life.You transplant a reproductive pair of fuzzy-wumpkins from a warm climate into a cold climate, and a second pair from the cold climate into the warm climate. As a control you also transplant a reproductive pair from warm climate back to the warm climate and from the cold climate back to the cold climate. You then measure the fuzziness of the fur of offspring that were produced by each pair. Part A: If the fuzziness trait had a strong genetic component (e.g. high heritability) what pattern would you find between parent fuzziness and offspring fuzziness. (Figure A, B, or C based on image attached) Part B: The figure below presents the results of the transplant experiment. The x-axis shows the transplantation site for each reproductive pair. The y-axis shows the fuzziness of their offspring. The color in the bars shows the origin site…

Among the Great Apes, yet unlike our chimpanzee and bonobo 'cousins', as humans we combine a unique evolutionary blend of different physical and behavioral traits commonly identified with either 'pair-bonding' or 'tournament' species. Which of the following options below inaccurately matches our shared characteristics with each type? Select one: a. moderate to high degree of sexual dimorphisms - tournament b. moderate to highly monogamy in coupled relationships - tournament c. male mate pickiness - pair bonding d. high parental investment - pair bonding e. females selecting mates for parenting skill - pair bonding f. moderate to high variability in male reproductive success & aggression - tournament

Cockroaches from the dormitories at Texas A&M University usually weigh about 1 gram. However, about 100 miles west of the university is a colony of much larger cockroaches in which some individuals obtain a weight of as much as 25 grams. These cockroaches of unusual size (COUS) have apparently evolved to consume the large supply of garbage that exists in the region. If a 25-gram cockroach is crossed with a 1-gram cockroach, their progeny grow uniformly to a size of about 13 grams. If two of these 13-gram (F1) cockroaches are crossed, cockroach sizes from 1 gram to 25 grams are produced. However, the 1-gram and the 25-gram cockroaches are rare, occurring at a frequency in each case of about 1 in 64.   If a 13-gram F1 cockroach is crossed with a 1-gram cockroach, how frequently are 9-gram cockroaches expected? Cockroaches from the dormitories at Texas A&M University usually weigh about 1 gram. However, about 100 miles west of the university is a colony of much larger…
