B. You could compare the sequence of the gene in different species and see the effects of different forms of the gene in genetically modified organisms.
This option allows for the direct comparison of the gene sequence in different species and the functional effects of different forms of the gene can be observed in genetically modified organisms. This combination of data would provide the most comprehensive understanding of whether a mutation in the developmental gene was responsible for speciation in the particular group of animals.
Which of the following gives the BEST example of data that you could use to determine whether a mutation in a developmental gene was responsible for speciation in a particular group of animals?
A. You could only use standard techniques to sequence the gene and see whether it differed in different species.
B. You could compare the sequence of the gene in different species and see the effects of different forms of the gene in genetically modified organisms.
C. You could use genetic engineering to turn the developmental gene on and off to determine what it does within the group of animals that interests you.
D. You could examine closely related groups of species to see whether they have the identical gene.
