Quizplus · Accepted Answer

To calculate the genetic distance between Species B and Species G, we need to compare their DNA sequences and count the number of nucleotide differences. 
DNA Sequence for Species B: TACCGGGCCATCGAAG
DNA Sequence for Species G: TACCGGCCTATCGAAC
There are 5 differences in the DNA nucleotides between them:
- The 4th nucleotide is C for Species B, and it's A for Species G.
- The 9th nucleotide is A for Species B, and it's T for Species G.
- The 11th nucleotide is C for Species B, and it's T for Species G.
- The 14th nucleotide is A for Species B, and it's C for Species G.
- The 16th nucleotide is G for Species B, and it's A for Species G.
Therefore, the genetic distance between Species B and G is 5.
