How could the Dog Genome Project potentially help researchers understand human diseases?

A. Treatments that are successful in treating human diseases may be used to treat similar diseases in dogs.
B. The genes in dogs that cause diseases that are similar to diseases in humans may be caused by a similar gene.
C. Mammals such as dogs and humans have the same genome and, therefore, are affected by the same diseases.
D. Copies of normal, healthy genes in a dog may be inserted into human cells to cure a disease.

B. The genes in dogs that cause diseases that are similar to diseases in humans may be caused by a similar gene.

By studying the genetic similarities and differences between dogs and humans, researchers can identify genes that play a role in both canine and human diseases. This can lead to a better understanding of the underlying genetic mechanisms behind certain diseases and potentially identify common therapeutic targets that could benefit both species.
