A scientist is studying two previously undocumented organisms to determine how environmental conditions affect phenotype express
ion. In one study, the scientist determines how temperature affects the growth rate of these two organisms. The graph below depicts the data gathered by the scientist:
Based on the data collected by the scientist, which of the following is the most appropriate conclusion?
a) The two organisms are different sizes.
b) The two organisms are from different species.
c) They have the same genome response to temperature.
d) They occupy the same niche.

Answer:
the genotype of the parent guinea pigs are as follows:
RrBb (rough, black) and Rrbb (rough, white)
Explanation:
Since the phenotype of smooth coat is present in the offspring, the parent genotype cannot have RR alleles for their coat. Similarly, the rough, black parent cannot have BB alleles in its genotype because that will not yield a white coat color in its offspring.
After making the dihybdrid cross, the probability obtained for each phenotype is given below:
rough black:
rough white:
smooth black:
smooth white:
Hope that answers the question, have a great day!
