schematic of a diploid and triploid Grass Carp red blood cell

A schematic of a diploid (top) and triploid (bottom) Grass Carp (Ctenopharyngodon idella) red blood cell hematologically stained shows a smaller brown oval representing the nucleus. The larger, red oval depicts the cytoplasmic material surrounding the nucleus. The overall shape of the diploid cell is more rounded. Potential metrics for training the machine learning model are denoted with letters “A” (cell length), “B” (cell width), “a” (nuclear length), and “b” (nuclear width), as well as the general shape of the nucleus.
