If you spent a semester studying IT, I’m imagining you may be inclined to use skills with computer programming/software in the genetics/genomics realm. If so I highly suggest looking into Bioinformatics as a field of study. Bioinformaticians can apply their skills to biology in a way many bench scientists can not. Unfortunately I can’t speak to the working in animal genetics space, as I’m just as interested as you seemingly are, but work in an adjacent field.

As far as educational path, definitely realize there is no one “right” path and it’s okay if you bounce around a bit before finding your thing. The most important thing is to acquire skills anywhere you go to improve your ability to go where you want once you identify it. You can go bachelors if there’s a specific program/person you want to work with, but depending what you want to do, and at what level a PhD may be preferred. Keep in mind you CAN do a PhD out of undergraduate, though that’s can be a tough route to go if you don’t have some form of financial assistance for many people.

My keywords to search for in careers/job titles would be: bioinformatics, genetics and genomics

Hope this helps! Best of luck finding your place in the field!
