Remember that this chart is for BA, not BS degrees. I didn't even know a BA in Biology existed. But apparently it does:

The BA degree often allows more room for outside electives. This can be especially useful if you are trying to double major or minor. BA students usually still go on to med school, but some prefer to go into other fields like teaching or software engineering.

BS students typically take fewer general education requirements and more science and math courses. Additionally, BS students have the option to specialize. You should consider a BS degree if you are sure of what you want to concentrate on during your college career.

So, it's "biology-lite". Unsurprising that women would dominate the watered down version of a science degree
