One of the reasons that pufferfish are a good species to compare to humans is because
A)it is so easy to hybridize the two and investigate the consequences.
B)they are so distantly related that it's easy to distinguish mutually conserved sequences.
C)the introns are often identical.
D)of the rapid response time in pufferfish to artificial selection.
E)they have been separated for so many millions of years and yet the gene sequence is almost identical.

Question

Quizplus · Accepted Answer

Pufferfish and humans are distantly related, which makes it easier to identify sequences conserved across both species. These conserved sequences are likely to be important for biological functions, making them of interest for comparative genomic studies.
