Here are two tools you can look at when thinking about your chances:
Admissions by source school (high school), click on tab “Fr GPA by Yr” or “Fr GPA by HS” to see average admit GPA for your own high school: Admissions by source school | University of California
Admissions by discipline: Freshman admission by discipline | University of California
From the above tool, here is a screenshot of GPA ranges for life sciences majors at each campus from the most recent year that the tool has data (2024):
I would say UCM safety, UCR and UCSC likely, UCD target or low reach, and the rest would appear to be reaches. (And keep in mind that UC is holistic, so reach doesn’t mean you can’t or won’t get in… just less likely.)
