Answer:

37

Explanation:

Since the Gruffalo has a somatic chromosome number of 67 and the Buffalo has a somatic chromosome number of 60, we may infer that seven chromosomes from the Grizzly were not able to pair up with the chromosomes of the Buffalo. Checking the options, the only choice that has a suitable number is b. 37 chromosomes. If this is true, then the remaining 30 chromosomes were able to pair up.
