Biography

Hi! My name is Aria Rotbart. I am a 3rd-year human biology major at UCSD with a minor in global health. I am on a pre-health track looking at a career in veterinary medicine. My entire life I have loved learning and loved to teach people about the things I care about. I volunteered at libraries helping kids to read, I led teaching groups for the younger kids at my local Pony Club and helped them to better understand horse care and prepare for their Pony Club tests, and I spent countless after school hours helping local school kids and also my lower classmen understand the materials being taught to them. As I entered college I found myself faced with a wealth of information I had yet to understand, but I fully engaged and embraced that lack of knowledge as an opportunity to push myself to learn more and expand my horizons. Now as I near the end of my college career I would love to be able to share that knowledge I have cultivated as well as inspire other students to be ambitious and to put in the hard work to understand a topic that is challenging to them. Knowledge is a powerful thing and I would love the opportunity to be able to share that with other like-minded academics.

Concepts of Biology

In pea plants, round peas $(R)$ are dominant to wrinkled peas ( $r$ ). You do a test cross between a pea plant with wrinkled peas (genotype $r r)$ and a plant of unknown genotype that has round peas. You end up with three plants, all which have round peas. From this data, can you tell if the parent plant is homozygous dominant or heterozygous?
