Help please a. Describe the kind of symbiotic relationship that exists between the Hawaiian bobtail squid
and Vibrio fischeri. Describe the most likely cellular mechanism that Vibrio fischeri use to
determine their population density. (2 points)
b. Construct a graph that depicts the relationship between the percentage of Vibrio fischeri in
the Hawaiian bobtail squid light organ and the mortality of the Hawaiian bobtail squid. (4
points)
c. Explain why the mortality of Hawaiian bobtail squids increases when the percentage of Vibrio
fischeri increases AND decreases in the special light organ. (2 points)
d. Predict how the symbiotic relationship of Vibrio fischeri and the Hawaiian bobtail squid would
change it Vibrio fischeri stopped producing light but still lived in the special light organ of the
Hawaiian bobtail squid. Justify your prediction. (2 points)

This problem has been solved! see the answeryou are investigating two traits in fruit flies controlled by one gene each. the b gene controls for body color (black or brown), while the r gene controls for body sculpture (rugose or smooth). after crossing rugose black flies with smooth brown flies, you obtain an f1 generation of 100% smooth black flies.what are the dominant alleles? (1 pt)what are the genotypes of the two parent flies to perform a dihybrid test cross? (1 pt)after running a dihybrid test cross, you find 1000 offspring with the following phenotypes: , rugose406black, smooth86brown, rugose94brown, smooth4141000fill in the expected column with the expected number of offspring in each class of phenotypes. (1 pt)what phenotype classes represent the recombinant offspring? (1 pt each)calculate the relative genetic distance between the body color gene and the body sculpting gene (show your work). (1 pt).
