ou are researching reptiles and encounter two garter snakes on a hike. Both snakes are brown and white, but their patterns are slightly different. You bring them back to the lab for further study. What is the BEST way to determine if these two are the same species?

Question 3 options:

Their appearance - if they look similar, they must be the same species


Their adaptations - if they have the same traits, they must be the same species


A breeding experiment - if they are able to produce offspring, they must be the same species


DNA testing - if their DNA/genes are the same, they must be the same species
