William & Mary or UC Davis for biology: which is the better fit for an undergraduate biology major?

For an undergraduate biology major, William & Mary tends to fit students who want a smaller, more personal academic environment, while UC Davis tends to fit students who want the scale and breadth of a major research university. William & Mary is known for close faculty interaction, strong undergraduate teaching, and an atmosphere where advising and mentorship can feel more accessible. UC Davis stands out for the sheer range of biology-related research, labs, and specialized areas, especially if you want to explore fields tied to agriculture, ecology, animal science, genetics, or public health.

A student who learns best in smaller classes and wants professors to know them well may feel more at home at William & Mary. Intro courses can still be sizable, but the overall campus is much smaller than UC Davis, and many students find it easier to build relationships with faculty earlier. That can matter for research access, recommendation letters, and day-to-day academic support. If you want a biology experience that feels discussion-friendly and advising that is less easy to get lost in, William & Mary has a real advantage.

UC Davis makes more sense for the student who wants lots of options and is comfortable being proactive. It has extensive biology infrastructure, many research groups, and broad course offerings across life sciences. For someone who is excited by a big university setting and willing to seek out office hours, labs, and faculty connections, Davis can open more doors simply because of its scale. The flip side is that advising and registration can feel less personal unless you take initiative.

For research specifically, both schools offer undergraduate opportunities, but the experience can look different. At William & Mary, there may be fewer total labs, yet undergrads can sometimes get meaningful involvement earlier because the environment is smaller. At UC Davis, there are far more labs and subfields, but competition and navigation can require more persistence.
