About Paper:

Our study aims to investigate how genetic variation influences developmental growth patterns in zebrafish. Specifically, we compare the growth trajectories between wild-type (WT) fish and arxa mutant fish across 239 UNIVERSITY OF OREGON • 2026 UNDERGRADUATE RESEARCH SYMPOSIUM TABLE OF CONTENTS developmental stages. The zebrafish were bred under controlled laboratory conditions and sampled at key times in their life cycle. Combined with microscope images and length measurements, we aim to obtain precise measurements of both types at developmental stages. Growth data were analyzed to identify differences at each developmental stage between genotypes. Our findings suggest that arxa mutants will be smaller compared to WT zebrafish, with impacts on developmental progression. These results can contribute to a better understanding of how genetic factors regulate an organism's development. This work has many implications for understanding the role of genes in development and growth regulation. It can also inform future studies investigating developmental disorders.
